I acclimated the fish for 3 hours and placed him in my 75 gallon tank. Initially everything looked ok. The next morning I found ich all over him. I do not have quarantine tank nor do I have the money to buy any tank right now. Currently I only have two damsels in the tank. Can I medicate him without having to use a quarantine tank. I read the warning signs with wild maroon clownfish and still got one. He looked fine at the pet store. All of my water parameters and salinity are at correct levels. Please need help!!
