This guy isn't eating, tried all types of food. First signs of ich appeared. He's been in my main tank since day 1 since the store had him over a week with no symptoms and he was supposedly eating and qt can be tough for these types since they need space. My main tank is 175g and qt is 20g with cupramine copper meds. My plan is to freshwater dip today then either back to main tank or qt in copper 20g. Thoughts? Foods tried so far nls pellets, brine, mysis, zucchini, lettuce, algae pellets. Thanks! Need to act as I've seen this spiral before.
