pick sack thing?? 02/09/09
Since moving my tank, these strange pink sack like things appear in my tank at random intervals. When I scoop them with a net they fall apart. I assume it is some sort of waste material, but can not figure out where it comes
from. They are rather large 1-3 inches in length. Tank is 170 gallon FOWLR six line grouper, wolf eel, snowflake eel, dog face puffer, saddle back grouper.
Thanks in advance
<Mmm, given their shape, the falling-apart behavior... my best guess is that these are fecal pellets... What do you feed these fishes?

Re: Algae ID?!  02/06/09
Hi Minh,
<Hello Brian.>
I apologize! I thought that I had sent you the pics. I did look on your site (http://www.wetwebmedia.com/trialalgaeid.htm) and a few you mentioned below but still can't find anything that is similar to it. Hope these pics are clear enough to get a good view! Please let me know!
<I'm sorry but I still don't see any attachment with this email. Could you try to resend the message with the pictures attached?>
Thanks again for your help!
-Brian
<Cheers, Minh Huynh.>

Re: Algae ID?!  02/06/09
Ugggghh! Very Sorry Minh!
Here are some links to them in case they are getting stripped off.

Sorry for the inconvenience!! I really apologize!!!
<No problem, Brian. Technology can be so unpredictable. Well, I am finally able to see this algae and it is quite an interesting case! If it is indeed a type of algae, I don't believe I have seen this algal variant before. A typical long and white algae would be Acanthophora spicifera (http://www.reeflex.net/tiere/1619_Acanthophora_spicifera%20.htm) and the growth in your tank is quite different. Another possibility is a form of sponge like the Carteriospongia vermifera (http://www.reeflex.net/tiere/2202_Carteriospongia_vermifera%2002.htm). I will have to check with my colleagues and other resources to verify and get back to you.>
Thanks again,
-Brian

Mystery stuff growing in my established marine tank – 02/01/09
Hi, I tried to search through all I could at your sight and didn't come across anything I could find that would describe what this is in my tank. I attached 3 pictures, 2 of the one and 1 of the other. Here is what I have:
1.This white, almost leather looking stuff that has LONG stringy, root looking things growing all off it and around it. Doesn't seem to move. I took really great pictures so someone could help. I have this same white or off white leather looking globs on other rocks but the stringy stuff isn't growing there...all is gathered in the area you see in the picture.
<This is a sponge... a Poriferan... See WWM re... not deleterious>
2.The second question is this cotton ball looking growth, it actually reminds me of a dandy lion after you blow the stuff off of it. Its round in shape with short spike things all around it. Doesn't move either. The rock in the tank has been in my tank for years and these things are just now showing up. I can't think of any reason for the changes at all.
<Mmm, how large is this? It looks like an Urchin of some sort... may not move much... also not harmful...>
Any help to point me in the right direction would be awesome! Thanks! Leann
<Enjoy them! The sponge can be "cut back", the "Urchin" removed entirely if they bother you. Bob Fenner>
