Hey, new guy here and I had a few questions about what type of fish (cichlids) I could put in my tank. First of all, I am getting a 55 gallon soon, and I really want a fish that gets to be a good decent size 8-10 inches that is very aggressive. I was looking at these Pike Cichlids, but i'm not sure what type they are, they are a pale green, with a line from their eye to the end of their body, but it's not a solid line, its a broken up line, and there is a faint red color line on the dorsal fin. If anyone could tell me a little about the species that would be cool. And if anyone else has any fish in mind, let me know im open to all suggestions on fish. Thanks.
