Do Clams Ever Have Bad Days?
I have had a Derasa for about 3 months now, and the Clam has pretty much doubled in size. Everything has been going great, but for the last 3 or 4 days, it hasn't been extending its mantle quite as much as normal. The mantle does not look pinched and the Clam is not gaping, it's just not as "fluffed out" as it usually is.
* I have inspected the Clam for snails and/or pests, but I do not see anything. * I have noticed over the last week or so that the Derasa has changed its position about 90 degrees. It seems to be getting more light now because of this position, so I am wondering if its not extending as much because of this? * There have been no recent changes or new additions, but I have been removing Mushrooms lately. I wonder if the shrooms have been releasing chemicals which have made the Clam unhappy? I am running carbon just in case. But that's all that I can think of, so I am wondering: Kind of like Leathers, do Clams have bad days? Aside from not extending its mantle as much, the Clam looks perfectly healthy, but I am starting to worry. Thank you for any input!

I have a similar problem. My Derasa looks good, but never extends its mantle beyond the shell.
It's about 5 inches long, and has attached to the rock. It attached after only 2 - 3 days. It's about 2 feet directly under a DE 250 watt halide, so it gets good light. I kept it to the side when I first got it and moved it over the space of four days to the center where the 250 halide shines. It's in a 90-gallon tank, with lots of water movement, water parameters all good. When I bought it, the mantle was a drab brown, now it has a very nice iridescent blue striping. It's very alert, but never seems to open widely. Is this normal? |

I'm glad that you chimed in because I was getting ready to answer my own question.
I believe that Clams can have bad days. I recently removed some rock and rearranged some others, and I believe this is what caused my Derasa to retract a little and show signs of distress. It is back to normal now, almost like nothing ever happened. Quote:

I bought my Derasa about four weeks ago. It's about 5 inches long. Seems to be doing well - looks nice.
