04/02/09 Clean Up Crews...Would Like More Than One Member To Answer 1/27/09 Hi Crew, <Hello Sam> Caption does not relate to 'The Crew'. I would like various opinions from the Crew as to the benefit of snails etc to clean up the aquarium. I don't want to ruin anyone's business but I would like to know what the real scoop is. Let's face it, if you have an algae problem it is not going to be resolved by critters. You need to reduce the nutrients that feeds the problem. <Mmm, sounds like you have just answered your question.> And even for general cleanup does anyone have snails that clean the glass so that they do not need to clean it themselves. <I know of no snails that have evolved into squeegees. Most do a reasonably good job but none will ever get the glass squeaky clean. Snails have different feeding habits and need to be selected by the job you want them to perform. A good place to start reading is here. http://www.wetwebmedia.com/gastropo.htm> And they do add to the bio load themselves. <Will add little.> So is it useful to have them other than to have diverse life in the tank? <Yes.> Same question relates to the sandbed. <Bumble Bee snails are a good choice to help keep sand beds clean.> Thanks, <You're welcome, and no guarantees here whether other crew members will chime in as this is not a puzzling question. Googling should provide you with all the info you desire on this subject. James (Salty Dog)> Sam
Snails, Red Slime 1029/07 I was wondering for my 140 reef how many turbo snails would I need to keep it relatively low on algae. <Between 6 and 12 IMO, they really are pretty inefficient at controlling algae. Water changes and nutrient control work much better.> Also do you know of anything other then red slime remover that takes away red slime. <Again water changes and nutrient control. I would not use a chemical treatment here, will not solve the long term problem.> <Chris> Gastropods/Snails/Limpets and an Over Abundance 12/5/05 I'll save space and your having to read by not listing our tank setup - if you need to know the setup to answer this question, let me know and I'll oblige. <Okay.> We setup 90 gal tank with 130 pounds Fiji and Marshal island live rock about 5 months ago. Within a week, we found a large cap snail hitchhiker...5 months later, there's so many in the tank (also a few in the refugium) we lose count to get an exact number. I've read if you know how many snails you have, you don't have enough, <This sounds like a retailers slogan 'I to have heard such ludicrous rules of thumbs such as this one and the common 'One hermit and snail per gallon rule' which is to say the least ridiculous.> but is there such a thing as TOO MANY CAP SNAILS? <If you have an overabundance this means that there is sufficient algae to support them. The algae is fueled by nutrients. So if you want the herd to be naturally thinned out I would check your system for detritus build-ups and watch how much you feed. Water changes are your friend.> If so, is there a natural predator for them? <Yes likely any mollusk and crustacean predators such as wrasses and puffers. However they will not limit their predation to just your snails, your microfauna population would be adversely affected as well as any other small critters in your tank.> cheers <To you too.> Donna <Adam J.> What Snails Do You Like? - 01/10/06 Gotcha, Thanks so much
Eric. <<You're welcome Dave>> How do you feel about
Turbo snails, Trochus, or Nassarius? <<My problem with the first
two is, aside from being prone to die-off, they are like little
bulldozers knocking corals around as they prowl/graze...worse than any
urchin for this in my experience. I do like Nassarius
snails...and Ceriths are an absolute fave of mine. I also
have what I believe is a very small conch (1/4"-3/8") that
multiplies like mad and is a great little detritivore.>> Dave
Harvey <<Regards, EricR>> -
Snails and Hermit Crabs Dying - Hi: <Hi, JasonC here...> I
have had my system up and running for almost a year now with no major
problems. However within the last 2 months my snails and hermit crabs
have been dying. I have enough algae growing on the Live Rock to keep
them busy. My Ammonia and Nitrates are zero and the PH is 8.4. Any
ideas on what could be wrong? <Probably nothing - most likely a form
of natural selection at work, and none of these live forever... I
wouldn't be too concerned.> Thanks, Aram <Cheers, J --
> Clean up crew help Hi Guys, <Hi Louis, Don here tonight> I have a 55 gallon salt tank that has currently cycle very nicely with about 30-40 lbs of LR from Florida. Things have started to proliferate on the rock including green algae. Don't know if you would consider them Macros, but I don't think so. No real developed leaf structures. They are more grass like. All chem. levels at this point are perfect at 0 with Nitrates at 10ppm, temp at 77 deg f.. These reading have been constant for well over two weeks now. <Good for you, but if you are going with corals, need to see the nitrate at 0.> I would like to move to the next step in my tank process, but as always, due to past failures I am afraid to make the wrong decisions. <Nothing wrong with going slow, actually can be a benefit.> Can you suggest a combination (numbers and names) of snail/crabs etc that I would need to place in the tank for clean up? I have no fish at the point, and in the future I plan on only some simple soft leathery corals. Fish species still up in the air, definitely a Yellow Tang somewhere in the picture. Still learning about fish species. <I don't like using any type of crab. I had red leg hermits that decimated my snails and have moved to snails only. Astraea, Nassarius, Cerith, Trochus, a good mix is what you are looking for. Numbers will depend on the load of the tank. I would start with 6-8 of each except the Trochus, maybe 3-5 of those. See how they handle the clean up and then modify from there.> Lastly, I would like to continue as well by adding another 30+ lbs of LR and probably stop there. Would it be detrimental to add the LR to the tank to cure at this time? Will it hurt the current flourishing LR? Can I add the clean up critters simultaneously with the next batch of LR or do I need to wait out the next cure phase before moving forward on inhabitants? <If you are going to add more rock now, I would wait to see if there is an ammonia/nitrite/nitrate spike, maybe a week or two. Then start adding livestock.> Thanks so much as always. Louis Rizzo Selecting a "Cleanup Crew" Hey Guys <Scott F. your guy tonight> I am somewhat confused about what "critters" to use for cleaning up detritus etc. I have had a few crabs, a few snails, and some shrimp. I need to purchase a restock of "critters" Could you give me a list of the BEST ones? <Well, it all depends on what you need them for...If you're looking for algae control, you may want to consider Strombus, Trochus, and Turbo snails. I like some of the herbivorous hermit crabs, too. For detritus control, you could look into some of the so-called "Margarita snails", or the interesting "Sandbed Clams" that you can obtain from my favorite source, Indo-Pacific Sea Farms in Kailua-Kona. IPSF has a great selection of "cleanup crews" and diversity animals...Inland Aquatics, LiveAquaria, and other e-tailers offer a variety of animals that can do the job nicely....Do check out the many possibilities...Hope this helps! Regards, Scott F> Thank You Rudy Cleaning Crew Run-Down Ryan, thanks for taking the time to answer my question. <surely!> I have read the FAQs re: sand sifters and decided against the sand sifting star. <You'll be glad, believe me.> This time around I would like to let the animals do most of the clean up work. When I stated in the previous email "an assortment of snails", I was thinking about Nassarius, Cerith, Bumble Bee, Turbo, Trochus, and Astrea snails. <Nice assortment, but you may starve this many snails without a heck of a lot of algae. Turbo and Trochus seem to be the most productive in my tanks. My bumblebees are a bunch of freeloaders!> I've read that these guys should help with the detritus and algae. <Yes, to an extent.> Just how many do I need for a 125g tank? <25-35 max. Start with 15, add them as your tank matures.> Also, I've had a problem with Blue Leg Hermits eating my Astrea snails (not for their shells), and don't want this type of hermit again. <Most hermits are opportunistic by nature.> My Scarlet reefers have never bothered any of my snails, and I like them a lot. Would about 50 of these guys be sufficient or should there be a mix of hermit species? <50 is way too many. Try 20 to start, and see how this works.> I was also thinking of a sleeper goby, but don't want to have him starve. <Skip it. Not sure what kind of aquatic life you plan on keeping, but many fishes will take care of algae growth better than a sleeper goby.> What would you suggest re: a clean up crew for a 125g? <My "dream team," first off, would include a refugium. Prevent the algae from growing by diminishing the available nutrients. The snails and hermits sounds fine. Look into opisthobranchs, commonly known as Sea Bunnies. A great algae eater for bigger setups. Also consider Cypraea annulus. What I've found with grazers is that diversity is the key. Each of these animals occupies a different niche in nature, and therefore in your tank. The more diversity you add you cleanup crew, the less you'll have to intervene. Talk to you soon! Ryan> Thanks again for your help and patience with my questions. Re: Initial Clean Up Crew Thanks again. How many snails and/or crabs do you think I would need initially? <None... please see WWM for input on such crews, selection> To refresh, it is a 440 gallon FOWLR with about 210 lbs of live rock, no fish in the tank yet. The substrate is CaribSea Aragamax Sugar-Sized Reef Sand: 0.2 - 1.2mm diameter grain size. It is about 1-2 inches deep so I don't see much need for deep burrowers. Since there is no fish, I guess the only food initially will be any debris off the rocks and coralline algae. <Yes. Bob Fenner> We Need Merry Maids! 11/12/2005 Hello WWM Crew, I hope all of you folks are doing GREAT and as always, thanks for the wonderful website! I am almost completely cycled and getting ready to start stocking my 240 gallon reef tank and I think I have most of my livestock list figured out except my "cleaning crew". This has been the most confusing aspect of figuring out my livestock list thus far and was wondering if I could get some advice. My first question concerns the Nassarius obsoleta or Ilyanassa obsoleta. I was considering adding some of these to my cleaning crew for their glass cleaning, algae eating; sand stirring ability but I have read so many mixed reviews I am not sure what to do. <"When in doubt, leave them out"> One person swears by them and the next person condemns them. I was wondering if you would give me your opinion and/or experience with them, whether or not you recommend them and if you do recommend them, <Are useful creatures of utility for many types of marine aquariums, species mixes> how many you would recommend for my 240 gallon tank? <A handful, two handfuls> I have 500 pounds of rock (250 pounds base rock/250 pounds live rock) and an average sand depth of 2". Also, I am including what I have come up with for a cleaning crew and I was wondering if you could advise me whether you feel this is appropriate for my setup or not and if I should add the N. obsolete along with this crew, substitute if for one of the other snails or leave it out all together. I haven't purchased any of these items yet because I don't have a LFS or anyone locally to ask advice and to be totally honest, you folks are the only source I trust when it comes to my reef tank. I also would like your opinion as whether I should add this cleaning crew first or should I add some of my other livestock first <They, the cleaner-uppers, should go in first> and wait a few weeks before adding my cleaning crew so they won't starve on such a new tank. <Not likely with the LR> Anyway, the cleaning crew I have come up with is as follows and please direct me as to whether you feel this is appropriate or as to what changes I should make. The list is as follows: (50) - Mexican Red-Legged Hermits Clibanarius digueti, (200) - Small Blue-Legged Hermits Clibanarius tricolor, <Am not a big fan, okay even mid-sized fan of using Hermits, and not in large numbers... I would start with far fewer if you want to use these> (120) - Turbo Snails Astrea sp., (120) - Nassarius Snails Nassarius vibex, (30) - Nassarius Snails Nassarius polygonatus, (30) - Nerite Snails Nerite funiculate, (120) - Cerith Snails Cerithium strercusmuscarum and (6) - Peppermint Shrimp Lysmata wurdemanni. <... this is way too many snails... by about an order of magnitude in my opinion/experience. Many will die off... polluting your water, others will "die mysteriously" consumed by the Hermits...> I am sorry for such a long email but I just want to make sure I am on the right track before adding such a critical component to my reef tank. As always, thanks so much for your help! Take care all, Bryant <Please read here: http://www.wetwebmedia.com/marscavart.htm and the linked files above... Do agree with you re differing opinions in this hobby interest... And mine is to scrub more, circulate, aerate and skim more... be careful re introduction of the means of algal and detritus production, and severely limit the introduction/use of such "cleaners". Bob Fenner> Clean up Crew I'm putting together my clean up crew for my 46 gal. tank w/ 65 lbs. of live rock with lots of Algae. Would you recommend a combo of Turbo and Trochus or Turbos and Astrea snails? How many of each for my size tank? Thanks, Rob O. >> Well... you've asked a pointed, defined question... So... I'll gladly respond in kind. I don't encourage the stated stocking density of Trochus genus Snails, and I do favor the use (if being utilized) of Turbo and Astrea genera gastropods over the use of Trochus... (though in Europe... there are some collected/collectable Trochid family members that are desirable...). Bob Fenner Thanks Bob for answering the question of what kinds of snails. How many would you recommend for my size tank? <Oops, sorry for missing this part previously... IF I was using snails, five or ten of Astreas and Turbos... Some Blue Legged Hermits... again five or ten... depends on the types, amounts of live rock used, lighting... other algae eaters... am a bigger fan by far of using fishes... like Ctenochaetus Tangs, Blennies...> I also really want to get some starfish. I was thinking (1)Blue Linckia,(1)orange marble and (1)brittle starfish. Should I purchase these when I get my clean up crew or should I wait until my tank is more established? How many would you recommend for my size tank? Right know the tank is 6 wks. old with lots of Algae mostly brown). <I'd only consider the middle species... and you can place it now... or wait Bob Fenner> Thanks again, Rob O. Astrea snails and coralline algae Greeting and Salutations Bob or Anthony, <I'll take the salutation, and raise you a "Whassup?", Anthony> Quick question for the experts: I just added some nice cured LR to my system with some beautiful purple coralline algae growth. This morning I noticed one of my Astrea snails "sitting" on top of the coralline on the rock. Will these little guys eat the good (translate: pretty) algae or will they restrict themselves to the green stuff? <they will only eat microalgae and they favor diatoms (brown algae)> Thanks so much for all the time and quality you guys put into WWM. I hope you're raking in crazy loot with the advertisers otherwise I'm sure there would be many willing to pay a small subscription fee! <actually the wine, roman parties and dancing girls nightly are payment enough> PS-Anthony--didn't realize you were from the 'burgh, me too! Any recs. as to places for good quality live stock/LR around here? take care my friend. <Adam...too cool. Yes, reasonably good stores... what part of the city are you from? Perhaps your best networking might be through our local marine society. We take frequent road trips (subsidized by the club) to the best regional stores within a 6 hr drive! We also have great speakers like Bob Fenner and Eric Borneman annually just to name a few. Do look us up at www.pmas.org or contact me if you'd like more info. I hope to meet you someday, bud. Kindly, Anthony> Cleanup Crews Hello, What would you suggest as a cleanup crew for a 215 reef, mixed fish and invert? <It really depends on the tank; lighting, nutrient export, stocking, feeding, etc. all play a part.> Is there a general rule to follow? <The only rule I have is to use a variety of creatures and monitor what thrives/works. Astrea snails mixed with Turban snails, limpets, etc.> I currently have 180 Astrea snails, 100 scarlet hermits, 8 serpent stars, 5 sand sifting stars. Is this overkill? <Not enough variety for my tastes, way too many hermit crabs (probably soon to be a lot fewer snails), and I do not recommend the sand sifting starfish.> Do you even recommend sand sifting stars or are they not reef safe? <They are "reef-safe" in that they do not eat corals, but they must eat worms, pods, and other sand life to live. Most times they scour a sand bed until nothing is left and then they starve and die.> Thanks, Steve <You are welcome. -Steven Pro> Janitor Crews & Buying Liverock Hello, Reading a lot about the importance of cleanup crews on the web. Everyone has a little different opinion on what to have. Can you give me an idea on what I should get as a clean up crew for a 90 gallon. <The reason everyone has a different opinion is every tank is different; lighting, feeding, stocking level, nutrient export, water change schedule, etc. All of these play a role in determining algae growth and detritus amounts. The easiest thing is to start low and add over several months until you get a group that fits your tank and your style. I like to use a variety of snails, but keep the crabs to a minimum. I only like the Scarlet Reef Hermits.> I will purchase 90 pounds of live sand, and approx. 180 pounds of live rock for filtration. <You may get some janitors in with your sand and rock, too.> Do you have a suggestion on where to get the sand and rock. I have been on Tampa Bay Saltwater recently. <I am partial to rock of Pacific origin. If you purchase rock through mail-order or e-tailers, please cure the rock in a separate vessel regardless of what they say about it already being cured.> Thank you, Dan <You are welcome. -Steven Pro> Clean up crew issues Dear Bob, <Anthony Calfo in your service> A quick question for you. First the details. I have a 75 gallon tank compact fluorescents and 90lbs of Fiji live rock - just done curing. <I thought I smelled something when I opened this e-mail> I just purchased a classic clean up crew rated for a 50 gallon tank, figured I'd start small. The clean up crew consists of: 10 Scarlet Reef Hermits 20 Turbo / Margarita Snails 30 Red Leg / Left-Handed Hermits Now after being in the tank for only two days they seem to have eaten almost all the visible algae on the rock. <yes...they were added too early and now the ability of microfauna in your sand bed will be compromised> Should I start feeding them? If so what? <most are omnivores. add a mixed frozen meaty food (like Formula 1 and 2)sparingly 1-2 times weekly for starts until they can get incidental matter from fish and coral when your livestock inventory builds> Also could you recommend a place for me to buy bigger hermit shells. <some bags of coarse beach sand have tons of shells in them and it is cheaper than buying shells by the piece> I heard the hermits will eventually snag the snail shells. <true> Thank you in advance, <do consider tapping a refugium inline (above) the system and QT'ing the critters until your sand bed establishes a bit stronger. Otherwise, don't expect to see too many cool worms and critters in your sand> Simon. <regards, Anthony> Cleanup Crews I have two mated pairs of seahorses. I want to purchase a clean up crew from Flying Fish Express, but I don't want any harm to come to my animals. Are all snails and hermit crabs compatible in my tank? I have a 75 gallon tank, with 75 pounds of live rock and crushed coral substrate. My tank is over a year old. I have a bristle star, mandarin, blenny, Firefish, and a few corals. <I am not sure which package you are looking at, but will give you some general recommendations. FFE has the "Classic" Cleanup"¢ Crew and Reef Relief"¢ Cleanup Crew, both for 75 gallon tanks. I am not a fan of these package deals. I much prefer to buy individual groups of animals. I generally steer clear of any hermit crabs and avoid the green Mithrax crabs to. All of these guys are opportunistic omnivores, which means they can and will eat anything they choose to. A few others I do not keep would be any cucumbers and sand sifting starfish. I do like to use a variety of snails; Turban, Astrea, Trochus, Nerites, Cerith, and Abalone. -Steven Pro> Re: Clean up crew Why an abalone? They are very expensive. I purchased one and have been reading up on them, but I was just wondering why you suggested this animal. <they are AMAZING and incomparable herbivores once established><<Make sure you get/use a tropical species for warm-water systems... Almost all Haliotids sold in the trade are temperate animals... won't live... RMF>> Snail & Hermit Crab waste Hi Bob: My tank finally cycled
with a lot of algae bloom. Two days ago I added 10 Scarlet Reef Hermits
10 Turbo/Margarita Snails and 30 Red Leg/Left-Handed Hermits from
FFExpress. They have done an excellent job cleaning but I noticed a lot
of waste since I added them in the tank. Is this bad for the tank? And
should I pull out some of the hermit crabs out? <You neglect to
mention how large your tank is. I would not use anymore than 1 hermit
crab per 10 gallons. I use about 1 snail per 2-4 gallons depending on
the tank, lights, etc.> Thank You, Aram <You are welcome. -Steven
Pro> Help with basic snail id - predatory or not? Hello, I wasn't sure if this was the place to email for help with identification. I have a 20 gallon tank up and running and everyone is happy. I am just starting a 55-gallon tank. A friend of mine gave me all his live sand/rock from his salt water tank which he's converting to fresh water. I added it to my 55-gallon and notice this snail in it (see attached). Until the 55-gallon is established, I thought it would be better to put the snail in my 20-gallon tank - but I want to make sure it isn't predatory. My friend doesn't remember what types of snails he added, and I didn't see this type of shell online anywhere. I suspect it is just a harmless algae-eating snail, but want to make sure. He is purple inside. Thanks! Kari <Your snail looks like some kind of conch, but I can't be sure. Conchs have a long proboscis type mouth that kind of looks like an elephant trunk. They also have fairly large eyes on long stalks that extend upward around the edges of the shell. They also often bury partially in the sand. Compare the twist of the shell to another snail. Whelks are predatory and their shells spiral in a direction opposite that of other snails and have tiny eyes on a short stalk. Best Regards. AdamC> Gammarus attacking snails 8/19/04 Dear reefers, My quarantine tank has been "idle" for some time - i.e. no new acquisitions during the summer holiday period - and a large population of small amphipods has developed, presumably a Gammarus species. While observing the inhabitants ( I use surgeon's goggles and can see small creatures well) I noticed 2 Gammarus shrimps "worrying" a Cerith snail. They were picking at its flesh, and at one point extended a "string" of attached flesh. <Hmmm... These critters are often carnivorous on dead things, but few are predatory.> The snail did not seem too concerned and carried on feeding, but I do not think that the attention was doing the snail any good. I have had a couple of snail deaths in this tank over the last 2 months, and in each case there were Gammarus in the shell when I removed it. Is it my imagination or do Gammarus nibble at snail flesh if hungry? <As above, it is no surprise that the 'pods would eat an already dead animal, but it is very unlikely that they killed it. The shells also make an outstanding home! I suspect that if they were doing harm to the snail, it would retract into it's shell. A simple solution that will prevent this problem (if it is a problem) is to add some food for the 'pods. Some fish food or crumbles of meaty sea food will work very well.> Would it be a good idea to add a Rainford's Goby to the quarantine tank - no fish in there otherwise - to reduce the Gammarus population, or will the Rainford's eat my baby Cerith ( Dove ) snails which breed in the tank? The baby snails range from only 2 millimetres long. The adults are only 1/2 inch long. <A Scooter blenny, Mandarin fish or six line wrasse are all much better choices to reduce the 'pod population the scooter and mandarin are low risk to your snails, the wrasse is moderate risk.> Best wishes, and thank you for all your help in establishing a successful skimmerless tank - a year old now. Eric Brightwell FZS <Best Regards! Adam> Mystery snail ID 8/15/04 Hi there, how's things? I'm a long time reader, first time writer. My basic system is quite small (Despite all your good advice, budget would only allow a small tank). The main tank is 24 X 15 X 15inches, with an overflow weir falling into a sump complete with plenum (constructed as outlined in an article by Roy Eeke in "Marine World" July 2002), skimmer and being pumped back up at 2000L/h (minus whatever I lose in head pressure). <Sounds fine. There is nothing wrong with smaller tanks. A bit more attention to salinity and temperature are all that are required.> Anyways, I've been cycling this tank for several weeks (initially with a dead shrimp), ammonia spike is over, but nitrites are huge, so waiting waiting waiting. The shrimp was only in a couple of weeks, then whilst walking along the beach here in sunny Townsville, I picked up 3 hermit crabs and 1 snail (I then thought they'd make an ok source for ammonia, so removed the dead shrimp). <Good thought! I have never been a fan of the dead shrimp thing. Adding newly acquired live rock will provide plenty of ammonia on it's own.> I haven't been able to id any of these critters, but the snail is my particular worry (like to get rid of any dangers before I plunk fish in). He/she is a bit of a burrower, has an elongated spiral shell, mostly white with a black tip. Also possesses a proboscis. <It sounds like a Nassarius, but I am not sure of their distribution. Observe the direction of the spiral of the shell compared to that of a known snail. Whelks are dangerous predators, and can be ID'd by the fact that their shells spiral in the opposite direction of other snails. Don't use pictures since they can be reversed when printed.> Is this fellow going to be beneficial or a hazard in my tank? I've attached a pic, though not a very good one. I LOVE the site by the way, so many opinions from different writers, it's an absolute candy store for the marine reader! Thanks heaps for your expert time! Kind regards Ben <Glad you enjoy the site! It is most likely that your snail is perfectly safe, but do keep an eye on it just to be safe. AdamC.> Stocking "cleaning crews" (hermits, snails), lighting coral help on WWM Bob, Thanks for the reply. I've read the WWM sections about inverts and the quantity, and also noticed that you're not such a fan of these cleaners. <Yes> To be more specific, I have 20 blue leg hermits, 10 red leg hermits, 3 margarita snails, 8 Cerith snails, 5 Astrea snails, 1 peppermint shrimp, 1 cleaner shrimp, 1 serpent star fish (only 4-5"). Can you give me your insight on why you don't agree with so many inverts? <In a small volume (your 24 gal. cube in this case) the hermits often "cross the line" between being scavengers to predating desirable organisms... including each other... The snails die, en masse sometimes... and their dissolving takes most everything with them...> I read somewhere that this many inverts was the perfect amount to keep an almost maintenance free tank for a 24 gallon tank. Were they just full of B.S. so that they can sell their product? <Mmm, well.... there is at least a "difference of opinions" here... there definitely are a bunch of "pro" cleaner uppers as well as "cons"... Each must decide for themselves... but if you take a look in the wild, you will see there are few parts of natural reefs so arrayed> Also, currently I don't have any corals, how many hours should the lights be on? And how many hours if I do get corals? Thanks. Perry <Please put the terms: "lighting corals" in the Google search tool here: http://www.wetwebmedia.com/ Bob Fenner> Clean Up Crew For Overstocked Conditions - 02/10/06 I have a 46 gallon bowfront aquarium that I have had set up for 8 months now. I am wanting to add some sort of clean-up crew to help me with keeping this system as healthy for my fish as possible. I have done a lot of research as far as what's compatible with my other fish (a 4-inch Niger trigger, a 9-inch snowflake eel, and a 5-inch emperor angel). <<Ack!! Too much fish flesh for this tank my friend!>> I know this is too small of an aquarium for these fish and I'm planning on getting one twice this size around April. <<Mmm, may do for a year or so...really need one twice again that size for this mix.>> I am constantly getting these algae bloom, mostly red and green and some brown, <<Likely due to the "overstocked" condition of the tank.>> in my tank so I was wanting to get something to control it. <<Better to address the cause...>> I recently went to my LFS and I purchased 8 blue hermits and 3 Mexican turbo snails and introduced them to my tank without any problems. Everybody's getting along without any disputes. I was told by my LFS that I should get 7 or 8 more hermits and a 5 more snails... is that to much in a tank my size? <<You might get by with the addition of the hermits, though the Snowflake moray may take notice of them eventually and thin their numbers...but I wouldn't add any more of the Mexican Turbos to this size tank...if that's truly what they are.>> I want to get some sort of sand sifter as well so I wanted to know what you recommend. <<Do a Google search on sand-sifting gobies.>> Can you think of any other invertebrates that would be beneficial to my tank and be able to survive the other fish in my tank? <<Hmm, nope...not under these circumstances.>> Thanks for your help! <<Regards, EricR>>
