I have a little peacock eel in with my clown. I never really see the eel because the substrate is sand but they don't seem to bother eachother. At least i haven't had any fighting problems
Ok good... They will both be in with my silver aro now. The clown knife is very laid back. He is still really small tho about 4-5". The tire track will be about 7-8" when he comes in next week. Thanks for all the responses. Tyler
