About a week ago I purchased 2 true perculas. One slightly smaller than the other. Before purchasing them i had my water tested at my LFS and everything was good. When i first acclimated them they both were real healthy and ate well. I noticed that they started the pairing up process bvy the bigger of the 2 charging and the smaller one turning sideways and having his seizure like movements. Now heres the problem. For the past 2 days the smaller one is sticking to one part of my tank and will hardly move away from there. He wont even eat. The bigger of the 2 seems to be in perfect health..Active swimmer and great eater. Anyone have any insight on whats wrong with my smaller percula? thanks in advance
