This is probably a commonly asked questions so I apologize in advance, but are they really that bad? I've read they are nothing compared to the nasty of the stalsbergi. I've always loved their look but have been afraid to keep based on rep. I do also know that it depends on the indivual fish as well. However, here lately I have seen some posts and threads in different places that make them out to be relatively mellow in comparison to Oscars and JDs for example. Has anyone had any success in keeping these in a peaceful (relative) SA community with the likes of say severum, chocolate cichlid; festivum, electic blue acaras (hint: my community)? Lol Any rivulatus keepers have some insight? I'm going to upgrade my tank up from a 4' in the next few months and was considering trying one. I don't want to take any chances of my current fish being hurt or worse because a saum won't be tolerate. Thanks
