Hi, I've got a 75 gallon with a 3.5" male pink convict, a 3.5" female Jack Dempsey and 2 synspilum of unknown sex at about 3" each. I'm going to trade the synspilum back to the lfs because they are starting to take a beating from the JD and con. Any suggestions on what I could add instead that would be a better combination?
