I have had a Derasa for about 2 weeks now the firs few days it was wide open now it is closed. The other dau I noticed my Lawmower Blenny of all things picking at him mainly on the outside could this be the cause of the clam staying closed. My param are as follow:

PH 8.2
ALk 9.6 DKH 3.34 Meq
CA 330 (just doesed) Liquid Kent
NH4 0
NO2 0
NO3 0
MG 1350

Thanks

I had a large derasa and gigas. The derasa would never open as much as when I first got it, the Gigas always opened I was watching one day and my blenny was eating only off the side of the derasa. I swithched the clams and then the gigas started not opening as much, the blenny had to go. They are both doing well now, Good luck
