ive heard that dempsey is a mean fish and my friend is always braggin how tough it is. i was wondering if there is a cichlid i could get thats tougher than it and would win in a fight
with the above posts...there are a lot of species that are on average more aggressive than JD...but getting one just for that reason isn't really the best reason to get a certain type of fish. Besides, there'd be no way to actually prove it without putting them together to watch them fight which would be highly irresponsible.
