Bought a powder blue tang last week and put it in a quarantine tank. Well of course Justin's tank crashed and I had to throw all of his fish into my 55 gallon quarantine so the tank was very overloaded. So against my better judgement I moved my fish to my main tank. Now I'm worried about all my other fish getting ick. I know tangs get pick really easily. He hasn't been eating much since I got him. Today I going to try a different food and dip it in garlic to boost its immune system. Do you guys have any good ideas for this situation. I don't want to over or under react to this.
