I have a porkie puffer with ich. He,s in a 6ft x 2ft x2ft tank with a queen angel, blue throat trigger, foxface, mimic tang, flame hawk and a blue damsel. I want to remove them all and treat with hypo in hospital tank I have setup a 200litre corner tank with a couple of plastic pots in and a couple of pieces of rock skimmer and canister filter with uv. Will thiz be ok im worried its going to be to small and i may get aggression. No of the otger fish have signs of ich but wanted to clear it out of dt. Any advice would be great. Thanks
