I have a 30 gal
tank with a 10 year old parrot head named Leo. There were 2 small bumblebee sharks that grew larger than he. They were very aggressive and I donated them to a local pet store. All that's left are two catfish.
I would like to add some fast swimming fish (small) to the tank, but need advice. The sharks were good, but after they grew, were too fast and mean to other fish. One of them killed and ate a small algae eater. Leo is about 8 inches.
I noticed since the sharks left that he is losing his color. He's still orange, but it's fading. Only around his face is it still a bright orange. He's also not eating much and he used to eat whenever I threw 1-2 large cichlid pellets in.
Any suggestions for new fish or what could be wrong with Leo?
