Alright So I really want some African Cichlids (Mainly Electric Yellow Lab and something blue) and here are my choices put them in a twenty which is not a very good idea or put them in my 180 gallon with my other fish which also may not be a good idea but that is why I am here. In my 180 I have 2 oscars (one is 9 inch, the other is about 5 and yes I know someday I will have to get rid of them), 4 convicts (2 breeding pairs), a jack dempsey, 4 bala sharks, 3 clown loaches, 1 red tailed shark, 1 pleco, 2 columbian sharks (which will be on their way out) and one of the leporonis fish. Now I would like to add to that ideally 2 yellow labs, 1 blue, and 1 other "assorted african cichlid" i know water will not be a problem because of the farm raised, and i know diet won't be a problem because I give flakes and supplement with brine shrimp, and I am not worried about my other cichlids, so I just want to know if they will hurt my other semi-aggressive fish. Here is kind of the setup of my tank. There is the left area that is the convict place they have a few caves they breed in and kind of keep the caves to themselves. Then there is a another cave where the dempsey hangs out and keeps people away. Then there is a massive expansive of rocks that doesn't really have an owner and finally there is a last outcrop where the balas, cown loaches, columbian sharks, and red tailed sharks kind retreat to and I believe they do this because there is alot of open water above the rocks but they are not tied to that area like the convicts and dempsey is. So I have a large area of rocks, and I would like to add a bunch more caves and so basically if I do that can I add the 4 or 5 african cichlids or will they cause to much problem? I have never had them before so I don't know how aggressive they are compared to the oscars, convicts, and jack dempsey but everyone seems to be fine right now. So I apologize for the long winded question but please let me know what you think. Thanks
