Soooo..here's the situation, I'm really hoping someone can help me out. I'm fairly new to the aquarium keeping world, I've had a 75 g tank established for about 7 months now. I have a puffer that has been on and off with ich for a while now and now he's looking rather hot and bothered..he's eating, but other then that he's not looking so good. I want to set up a quarentine tank to put him in, but wonder if there's any point since it's obviously in my tank now..my huma trigger has it as well. I've been treating with herbtana, which has shown some success in the past with him, and did a freshwater dip today for him. Now as far as setting up a Quarantine, am i suppose to use water from the main tank, and then treat him with the appropriate medications, etc. Also I've heard yes to using a filter in Q tanks and no other places..would an aerator and frequent water changes due? Any help would be greatly appreciated!
