I wanted to follow everyones advice on stocking all of my cichlids at the same time but that was not possible because the LFS sold out. So yesterday they got some more in and I went and purchased one. It was an electric yellow just like the one I already have in my tank. I thought they would make a great pair. After i got the new fish acclamated to the temp and ph I released him into the tank. WAR.... the other electric yellow who has been in the tank for about a week freaked out. He started chasing the new one around the tank and has been acting like he wants to kill him. The new fish likes to just lurk around the top corner now, but the older fish still terrorizes him. His tail is nicked up aswell as his anal fin, and on his side back by his tail he has a raw spot with missing scales. I am scared that the older electric yellow is going to kill him. There are plenty of hiding places and caves in the tank, so I really don't know what else I can do. Please give me some advice, as I'm sure that this has happened to other people. I am hoping that the older electric yellow will eventually accept the new fish, but I'm not sure this is going to happen. Please help me.
