Kribs, firemouths (C. Meeki), N. brichardi (big brother and sister babysit). Dwarf jewels if you can find them Hemichromis. Lifilili or Cristatus. The last two are bright red with blue spangles and breed like convicts. Where are you located?
I think convicts are more in demand here than these gorgeous fish .

Fish demand is very local.
