I put him in my 55 gallon after I got him. He's in with some glass fin tetras, scissor tails, gnf, and a couple of guppies, the cats really keep to them selves. he hides almost non stop. When I do see him, he looks ok. Do you think he needs a tank by himself? Nobody in there would bother him. Everyone is pretty laid back. Just not sure why he is so upset. I thought he'd like a nice big planted tank. Any thoughts?
