After having issues twice now by adding fish to the tank without quarantining... I am learning to be patient rather than dealing with consequences. Both times I ended up with a parasite, and both times the fish came from a LFS that I will not mention because I feel they provide nice fish but it is my responsibility as a fish keeper to make sure newly introduced fish are safe to add to the show tank.
After my last issue, my girl Pork Chop even stressed to the point of showing a small spot of hole in the head. I feed high quality pellets (NLS, Omega One, Hikari, Xtreme) and do multiple water changes per week so I know it was not because I was not trying, but due to the stress I caused her by introducing a 'carrier' in the tank.
I will most likely pull her and treat with a bit of metro just to be sure. I have tried the Epsom salt in her food now for about a week. I have not noticed any real changes good or bad with her little spots so the meds are the next step. She eats like a pig and seems fine otherwise. With her in the 56g getting better, I will introduce the male pearsei to his tankmates and then bring Pork Chop back in with him. She is a big girl and I dont want her beating on her man.
