Okay, this is really weird, all my water parameters are in good shape, No1, No2, No3 all reading at zero now after two months of hard works...temp is at 78, salt level at 1.023, all my snails and hermit crabs are thriving...but just recently I got another clown to test out the tank again, but now the poor clown is not eating anymore and i can see the clown has closed fins, got it for a few days now, I was feeding both brine shrimp and dry food, but only a little at a time once a day...is something wrong w/ my water? is there some kind of hidden parasites?? although the clown show no visible signs of parasites...btw, this clown is the only fish in a 30 gal...I aclimated the clown using the drip method for an hour...HELP!!! I can't think of anything else that might be killing the clown...I'm about to shoot myself :frustrat:
