Any ideas as to what could cause a crocea clam to bleach? I got a small one ( about 3-4 inches) from a local frag swap a few months ago. When I first got it, it was a nice black with some blue.. now its almost completely white.. though it seems to be opening up ok.
I have it sitting on a rock near the top of the tank. I knew they like high light and to be on rocks with low-medium flow.
My lights are 2 x 150 watt MH and 2 x 96 watt PC ( one is 50/50 one is actinic) temp about 79-80 ( gets to 82 sometimes during the day over a peroid of several hours) calcium 400-420, alk 8, mag 1400, ammonia /nitrate/ nitrite 0
The only thing i can think of, late sept the tank got a bit warm since we had a heat spell here, ( tank was 86) and I had to add some cooler water ( in the sump) to cool it down. I also did run some phosban for a day .. it seemed bleaching has started after that.. but, the tank has been stable, no more phosban.. why is it still bleaching? is it getting too much light? ( I know they require very high lighting, however.. is this possible?) any help would be great.. I'm worried this little clam isnt going to make it. I'm a bit bummed.. I waited for several years and did lots of research before buying one.. blah!
Thanks in advance![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
