@MnFish1 @vetteguy53081 @Jay Hemdal i just noticed my royal gramma this morning looking ify with his scales looking like they are sticking out instead of flush with his body if that makes sense. You guys suggested fallow (which is no fish in the tank correct?) if I have a 20 gallon qt dosed with copper can I add all my fish into it, all my fish includes powder blue, royal gramma, 2 clowns, damsel. How how do I do it because I have a fear or taking the two and in a week or two down the line one of my clowns starts to look not the best, so if I put them all into quartile to treat them, can I put them in a 20 gallon together for 30 days or no? What would you do?
