Finally I got some decent picture after borrowing a MUCH better digital cam from my fren Picture appear much clearer and is up for comment
Anyway this is the whole tank pic- A 55 gallon tank(3 by 2 by 1/1/2)
Think so far there isn't anyway to cure the clam disease... The clam disease will spread to other clam(if i am not wrong) and usually its not from your water quality but actualy the disease is brought in by an infected clam(hey expert out there correct me if i am wrong)
nah when they MIA, in the end they always appear but take some time...
Anyway my fish understand me very well, so when they die, they will die in a spot that i could see clearly..... WEIRD.... probably don'y wanna let me waste effort in finding them
very unlikely too.... i have seen big bristle beside my clam before and nothing happen, most liekly a disease, or already having not enough lighting but you never notice or maybe even due to your water parameter
