I have had these two squasomma clams for three years now.One has started to bleach and the other has great color,my question is what could be causing this.The tank is a 75 gallon,I do 25 gallon water change every two weeks.The lighting is two 250 mhs,and flow is moderate.They are side by side in the tank.Any input will be appreciated. thanks

Well the clam didn't make it.I have no clue why one would bleach and die and the other looks great.

If the entire mantle was bleached, it is called generalized bleach which is caused by lack of nitrogen in the system. I guess the healthier one must fight and consume all of nutrient in the tank. I know when a clam get iarger, you have to increase fish waste with monitoring nitrate & po3 level. I keep xl trigger and angels in the huge refuguim for clam tank. The other cause for bleaching could be heavy metal poisoning. But for your case, hmp may not be a issue since the one is doing well. Good luck!
