Hey! Just saw this. Which fish has it and can you get it into the QT tank?
My QT tank doesn't have anything in it. It's a 10 gallon( that's all I could afford at the time) it has a filter ready to go, it's a AC50 if I remember correctly, heater and that's it. It's bare bottom also.
Does any of this help? Sorry about taking so long and sorry to hear about your sick fishy.
