I don't know much about fish, the tank is actually my husbands, but I noticed the two cichlids attacking our tire track eel. They were chasing him around the tank and pushing their way under our rocks when he tried to hide. We have a semi aggressive tank but everyone is pretty small, the cichlids aren't even 2 inches, our tire track eel is about 4 inches. We have a peacock eel as well who is only about 2 inches, but they didn't start messing with her til after I took out the tire track, so I took her out too. The peacock will pretty much hold her own but after watching the cichlids chew up the tire track I didn't want to take any chances. The larger cichlid we've had in the tank for a while and we didn't have any problems, it wasn't til we put the smaller one in that we noticed our eel acting strange. At first we thought he was sick, but he looks fine except for is tail being chewed up. Should we separate the two cichlids??
