I’m having difficulty QTing a clown goby. I had one in QT for 10 days then I lost him Shortly after treating him with copper. I went to the LFS and the kid working there was nice enough to give me another one. I put him in a clean tank and he died overnight. Is there something I’m missing that makes these guys difficult to QT?
is the a. Ore durable fish thats similar that I could try?
