Hi, they are beautiful fish with loads of character, rare and possibly extinct in wild so breeding them will help keep this species in the hobby. P.Polleni are the small spotted variety and P.Bleekeri are the large spotted variety. I kept mine in a 55gal on their own and they bred on a 3 month cycle, they are notorius for eating their eggs so are best removed and hatched in a egg tumbler device and are very caniblistic when tiny. Since moving them to a 6ft community tank they have not spawned for me. They are extremly aggresive with own kind but mix fine with other madagascans,frontosa,other mildly aggressive cichlids and rainbows as long as they are not too small to be swallowed. They love mysis shrimp, prawns and krill with tetra doromin and large cichlid pellets. They are tollerent hardly fish and can live in alkaline or acidic water but mine bred when the water was more acidic.
Would love to see some photo's of your fish
