so Im going to try and make this short without leaving to much detail out I think I had bought a possible sick six line about a month ago with ich that I added to my tank after the six line died some of my other fish died weeks apart (watchman , cleaner wrasse )without showing signs of ich maybe a spot here or there they would be gone by the next day so coming to present most my fish have died except my two clownfish and are doing perfectly fine I added a lawnmower and next day it was dead I’ve noticed my bigger clown Reyes to be territorial to even my hermits and I’m starting to wonder if it might be my clownfish he hasn’t killed the other clown but I notice he also doesn’t let the smaller clown leave a certain area of the tank (behind my hob ) I’ve tested my water parameters and have had same good water quality results just wondering what my best bet would be should I fallow or try separating my clown ?
