Lionfish mucus   11/25/06
Hello:
<Hi there>
I just got a fuzzy dwarf lion a week ago.  As I acclimate him to frozen krill and silverfish, his eating is improving.
<Good>
  Today, I notice a white mucus coming from him.  What is it?
<Mmm, a natural body exudation. Pteroines/Lionfishes produce, release a good deal of body slime/mucus in good health>
  Do I need to treat the water with something.
<Nope>
My LFS said E.M. tablets.  The tank parameters are good.  Thanks for the help.

When a Lionfish Does What a Lionfish Does..
>Hello all.
>>Hello one.
>I've Googled, and found no answer.
>>At least you made the effort.
>Yesterday I brought home a beautiful little fuzzy dwarf lion, who is the first occupant of my 75 gallon tank [along with 40 pounds of very crusty live rock]. 
>>Of all the things that should or should not be crusty, rock that is live, and bread.
>After recovering from the stress of the trip, he adjusted well, and even took a ghost shrimp for an evening snack. After lights out, he cruised the tank for several hours, getting to know the neighborhood.
>>Alright.
>Since this morning, though, he has spent the entire day perched on one of my heaters. I have not been able to find any information relating stress or transition to a need for additional warmth. I checked the temperature of the tank, and it's 76.8 F in the center of the tank, as well as at the front wall [measured 6" under the surface]. I have read that lions tolerate temperatures between 72 and 78 well, so I think I'm in the ballpark. Should I just chalk this up to WTTFJD [weird things that fish just do]?
>>Oh, no, not at all. This isn't weird in the least, either. This *is* what Lionfishes, especially dwarf lions, do. Simple as that. Marina

When a Lionfish Does What a Lionfish Does - II
>Marina,
>>Hello Rick.
>Thanks for your reassurance. I have learned some hard lessons with smaller tanks [harder for the fish than for me, I suppose]. I want so much for this tank to succeed that I might be overly fretful, and apt to turn molehills into mountains. After some further introspection, I suppose I was the same way with the first of my children.
>>Better to be safe, yeah?
>I came home tonight from a concert to find said little fuzzy guy cruising energetically, displaying for his reflection. I enjoyed having a nightcap and watching him being so active out in the open, illuminated by the moonlight LED's with the room otherwise dark. I'm thinking that such moments are the real reason we go to such effort to do this.
>>For those who get into the hobby in the first place, absolutely. For those who are "bitten", it can go far beyond that.
>Thanks again,
Rick Walters
>>You're most welcome, and I'm glad you can now enjoy your new fish. Marina 

- Dwarf Lion Growth Rate -
Hi, Great site.
A question that's I have searched, your archives, and all information I can find.  The question is, how long at the best guess, will it take a dwarf zebra lionfish, to grow from 1.75 inches to 4 inches. 
<A couple of years.> 
He is kept in a 40 gallon with 40 lbs live rock, a few mushrooms and a flower anemone. He is fed Mysis shrimp once daily now as he is still small. As he grows I'll feed silversides, krill, and chopped market shrimp about once daily or as needed. He eats very well, and I don't plan on feeding to much. The water is ph.8.3 , s.g 1.023, ammonia 0, nitrite 0, nitrate 5, calcium 400, dKH 12, temp 78. Thank you for your reply in advance, and yes I know he can/will get 7 inches or more when full grown, just concerned how long until he's 4 inches. 
<More than a year, but probably not less than two.
Cheers, J -- > 

Fu Man Chu Lion Questions
Hello Crew!
<Hello back. MikeD here>
Thanks so much for all you do and for the amazing amount of information you
provide.  I have searched the site and need more information on the Fu Man Chu
Lionfish.  Do they stay that small (one at LFS is 2 1/2 in.)?<While the books generally indicate a maximum size of roughly 4 inches, I've seen some five inchers over the years, quite likely very old fish that were caught late in life.>  Can I feed them
frozen food or do I have to invest in Mysis or something of the like?<As a rule, the Fu Man Chus are among the hardest to train over to non-living foods, although it can be done with some concerted effort.> We have a
very healthy 'pod population, keeps our Mandarin happy.  I have a gold striped
maroon clown hosting a bubble tip anemone, a mated pair of CBS, and a Mandarin
Dragonet, a green star polyp colony, 3 1/2 in DSB, and LOTS of live rock, part
made into a shelf which the CBS have taken over the underside as their lair.
Will these tankmates be ok?<No. The coral Banded shrimp will become food immediately, if not sooner. While the Fu Man Chus are not above eating a small fish, particularly if hungry, by nature they specialize in shrimp and small crabs.>  The Fu Man Chu seems too small to eat any of them,
but will that change?<Again, yes.  Don't be surprised to see a Fu grab a shrimp fully as large as itself and swim around for the better part of the day gradually swallowing until the whole animal disappears.  In extreme cases, they've been known to choke to death attempting to eat shrimp and fish larger than themselves.>  I'm sure he'll love the CBS's young, (every 3-4 weeks
they have more babies).  I'm sure it is not really possible to keep this fish
in my set up, but I was hoping it would be, my husband has been drooling over
lions for the past year!<Fully understandable.....I now have a 125 gal. tank and a 300 devoted primarily to larger lionfish and their kin, so be warned, once you make the plunge, they can be extremely habit forming.>  Our tank is almost 4 years old and seems to be doing
well.  I guess we are greedy, and need to get a bigger tank, ours is only 20
gal.  We also have a Refugium 13.25" X 4.5" X 12" and a good amount of constant
flow Penguin Sponge 170, Rio 600, and Rio 200 on the Fuge.  My husband's
birthday is coming up and I wanted to surprise him, but if this would be death
to the lion or my current fish, I'll leave him in the store.<Alas, at the moment this sounds like the wiser strategy.>  Alternatively,
when we do get a bigger tank could we use this 20 gal for a smaller lion by
itself if our current set up won't house him?<That is a definite yes.  In fact, a 20 gal. tank could actually house a pair of Dwarf Fuzzy Lions AND a Fu Man Chu all together if you so desire, which I suspect, you'd love.  I had a pair of Dwarf Fuzzy Lions that laid eggs 62 times over the course of 9 months...unfortunately, due to the extremely small size of the very numerous fry, and the fact that they need live plankton I was never able to successfully rear any, an ongoing hope (so far, to the best of my knowledge, they've never been reared in captivity). The Fu Man Chus will get along with Dwarf Fuzzies, but it's suggested that you keep only one per tank as they will fight to the death with their own kind in captivity, actually seeking each other out in tanks as large as 125 gallons !(yep, I tried that too! **grin**)  Thanks so much!  You guys are
always a great help!<Thanks for the encouragement...we try.>

Dwarf lion, zebra I think 
Hi, I just bought a dwarf lion. He is about 2 to 3 in. I have a 55 gal tank with a lot of hiding places, MAYBE THAT'S WHY I CAN'T FIND HIM ANYWHERE! I checked on him all afternoon and he was hiding behind a rock but now I don't see him. I should tell you that I also have a Niger trigger that is about 4 in long and a percula clown (Nemo fish) 2 in. I was told there shouldn't be a problem in my size tank?<no there should not be any problems> Well what do you think? Also won't the lion poison the other fish if he bits them?<The lions bite is not venomous...it is his dorsal spines which are venomous> He is sooo cute I hope he is alright and is just hiding.<he's probably hiding> Could you tell me if dwarf lions are active or our they hiders?<mainly hiders> Well I guess that's all the questions I have for 
now. I hope you can help. :-) Sincerely, Jill. P.S. I also have a lawn mower blenny and a med size hermit crab that is growing by leaps and bounds!!!!!!!<Good luck, IanB>
