Some cichlids are very NON aggressive... some are VERY aggressive...
Like i said, it just depends...
if you looking for some cichlids that would go with plecos ... that would be a better question to ask...
I have keyhole cichlids in my 75gal mudskipper / community tank. They are quite peacefull....
african cichlids and very large or very aggressive american cichlids do not do well with plecos. they can easily pluck their eyes out, which is the only part of a pleco's body that is vulnerable. (aside from their soft bellies - pirahnas will flip plecos over if they get hungry enough, but cichlids won't go that far)
I'd have to agree. The only cichlids I would put with plecos are VERY peaceful africans (which there are very few of) and dwarf cichlids from SA (apistos, rams, keholes).
I have a 6" Pleco in with my EBJD and Jack Females, they all leave him alone. I use to have FireMouths in with the Pleco, and the Pleco would harass the FireMouths more then they cared to harass him. So it all depends on the individual fishs temperment.
