Recently I made a new addition to my tank with a small hippo tang. I, yes this was a bad choice, didn't quarantine him, and you can probably already tell how this wound up. I've heard hippo tangs are ich magnets. As of now since he's been in my tank a few days he's seemed to be happy swimming around in all the open space around my two main rock pillars, but tonight I noticed that he was rubbing up against a rock repetitively and realized I had to make a decision fast or it would be a tank disaster all over again. I've tried many methods to get rid of ich and velvet in the past such as fresh water dips, and using hospital tanks with copper, and Ive decided to switch things up a bit. I've taken all of the inverts and coral out of my tank, and decided decided to leave the fish, rock, and sanded in the main display, and dose that tank with copper. This might not be the best choice, but I feel like it will work as far as really getting all of the parasites out of the sand bed and rocks in my main tank. Tell me what you think! I'm planning on starting copper tomorrow, and when I'm done with the whole process I'll use products to get the copper back out of the main tank. The water I used to set up the separate tank was made fresh and no water from the main was added. Tell me what you think!
