So I just got home and one of my new threadfin cardinals was dead in the powerhead. Little guy seemed to never adjust to his new home. I was warned on here that they weren’t known to do well in captivity. I’m reading 0 ammonia and got the whole fish out he wasn’t chopped up or anything. Is there anything else I should do? Trying to prevent more loss. All my parameters are in check every other fish and coral seems very happy
