So this is gonna be a little long! I have been downsizing my number of tanks (getting out of severum/angel fish breeding) and my final goal is 6 specialized tanks and one 350g tank with 1x BGK; 1x Watermelon Pleco; 1x Fire Eel. I have final stocking and full scale drawings of the aquascapes on all the tanks. However, I now have a buyer taking all of severums and angelfish and their tanks, far earlier than planned. The 350 was originally going to have a bunch of severums, then changed to angels, but now I realized a small issue... 1. Seeing as I'm selling all of the angels and severum early, I won't have access to my free stocking. 2. Thanks to a series of Facebook rants about bad fish keeping, I have been finding myself the new local fish rescue... at present the rescue fish I have are 2 peacock eels (they have a full tank designed for them, so they're covered); 2 angelfish, one with stunted fins; 1 Electric Blue Jack Dempsey; and 1 mystery satanoperca (not sure what kind yet because the pics I got were grainy and I haven't seen it in person yet, but I believe it's a daemon, yet he claims it was sold as a Lilith). And my best buddy, Satan The Reformed Homocidal Maniac Severum. I won't rehome the rescued, I made promises. All of these fish except the satanoperca (and the eels) are currently living together in total peace. My question is (finally), could I add any other top/mid dwellers with Minimal risk? I already know that this group gets along, but I was hoping to add some more SA/CA cichlids to just make it a variety hour! Any suggestions on some other SA/CA species that may work in this tank? (I have grow out tanks too FYI) also: Filtration = 2x FX6; 2x weekly 30% WC; plants (crypts, frogbit, Val, mosses); bubble wall.
