I had an aquarium when I was young, and last year got one again. Over all just the normal troubles with my fish, like some just don't seem to thrive, while others don't, same kind of fish added at the same time. So fish just do better than others I guess. I have an Eel and a Dinosaur fish, along with a Chines algae eater, rainbow shark, some barbs, a few gourami. I have two question can I get some catfish, I think they are so cute? Also, I would like to add live plants but the eel will dig them up, and ideas. Thanks, I have 55 gal tank
