Okay so I ended up with RD for my 55 gallon. I want to try him out in the big tank and move two of my smaller breeds to the 55 or one larger and one smaller over. Regardless out of these fish Rd, jd, gt, firemouth and syns who should go and who should stay to get my tank better distributed?In case you don't know my set up from previous threads I have the rd currently in a 55 and the others plus two oscars in the larger tank.

You will only know if the RD gets on with your Oscars and other fish until you try it. Just choose which one you want to move into the 55 gallon and see how things go. You probably get people giving you all sorts of different advice.

Yeah I know! Lol that's why I am trying him out since I have a good set up and good spots to hide. I just can't decide which to move so that's why I am askin. I've considered moving the firemouht and the syns together or the gt and the jd together. Can't make up my mind!
