do Tridacnids release bysall filaments?

[Ram_Puppy]

I have a Crocea that has been in my tank for a little over a month now sitting on a ledge. I gave him a nice little piece of LR to sink his filaments into.

this morning when i woke up and took a peek at the tank before running into work, I noticed a white 'fiberous' column where the clam used to be, the clam itself had moved into the sand, half burried, but mantle fully extended and looking very healthy.

wondering if he just decided he wanted a change of pace?

I am going to leave it where it is.

mine did that after the tank move. just released the old filaments, looks fine, it's been a couple of months now. i guess it will put down new ones.

in my experience they will move in that mannor

ok, cool... it's a very nice little crocera I got from CB, I am definately going to get more clams, I am truly loving this one.

jet black mantle with dark electric blue lines. very nice.

I want a black and white maxima, and a purple and black maxima as well. sadly, I haven't really seen many of these on the market in 2 or 3 years.

be very careful with your clam in the sandbed.... any powerhead that kicks sand up or any fish that will move sand can kill the clam very quickly.... experience talking here... just be careful.

thanks mathias, I don't have any sand stirring fish or inverts that would 'kick it up' and the koralia 3's are producing a powerful, yet suprisingly gentle current. I am very impressed w/ them.

the byssal gland is what the clam released and they will if they are not able to move. Meaning if they're attached then they release the gland and move on. Clams will regrow the byssal bundle and put down new threads with time. Thats very true about sand getting into especially crocea clam gills. The sand will clog gills and kill them
