So today I went with my friend to help him pick up a new tank for his room. A good deed never go unrewarded!
In the tank was a cichlid that the past owner didn't want, and my friend also didn't want since he only want his betta to live alone in the new 20 gallon tank he just bought (lol). Anyway this cichlid was apparently quite a troublemaker, since he killed all 5 of his tankmates, whom were also cichlids, along with his mate. That won't happen in my tank since my fishes can hold their own, but the problem is that i don't know what kind of fish is this guy. I'm also assuming he's a guy, since that's that most of us assume when we don't know the sex of the fish
Please help me out! Here are some pictures!
