Well I switched my 90 gal African cichlids tank to a south American tank . I saw these rare albino heckelii at my LFS and had to get them there so cute . I cleaned tanks changed the set up added driftwood. Have 5 heckelli ,3 red should severums and 1 gold/red severum mix and 1 pleco in there . Should more fish be added ? Tank has two fx-4's . Any suggestions would be great for success. Thanks
