I currently have a 5x2x2 150 gal. tank. I have a pair of GT 6.5 and 5.5 inches, a 7.5 inch male JD and a 6 inch female RTM, I also have a 14inch iridescent shark that will be going away soon. It doesn't change a lot but i have also a 12 inch common pleco. I want to have either a pair or a single fish in my 150 gal along with the pleco. I could keep my GT pair but the tank would be pretty empty. I was thinking about getting some festae for a pretty long time but was never able to find some where i live(MTL, canada) I'm looking for something that will be pretty imposing that will fill up the tank. I want a colourful fish. My current ideas would be to get either festae or synspilum because of their colour. I need suggestions of cichlids i could put in my tank that would probably be easier to get my hands on than festae.
