I have a 7" male dempsey who doesn't like to swim, eat, or play much anymore, his color is also fading, and his fins are kept to his sides instead of expanded beautifully. He's about 2 years old I believe, bought him when he was 2-3" and kept him for 1.5 years. He's very very peaceful and never eats meat or feeders. He's residing in a 75G with lots of goldfish and a pleco. He seems to be a lot happier with them than with my Oscar and Texas. Temperature is in the low 70s but I have put it at 80-82F to see if it would help and it didn't. Can anyone tell me what's going on with him?
