I have had an outbreak of ich in my tank. I plan to set up a quarantine tank tomorrow to medicate fish and allow tank to fallow for 76 days. My question is what size quarantine tank do I need for my specific fish/can fish go together in the same tank? I have 2 Bangaii cardinal fish, a starry blenny, two clown fish, and a long nose hawkfish. Currently one clown and the starry blenny have signs of ich and a yellow clown goby has died from ich. I think the goby may have introduced it to the tank.
