Hi, I would like to buy a new Polypterus endlicheri about 5 cm in size. I've had them once before, but unfortunately they died in a short time for an unknown reason. I'd like to find out a few things about them before I buy them again. What is the best way to feed them? What to avoid and what fish to keep them with? Is it possible to breed them with small cihlids from the beginning? So they don't bite their gills. How fast do they grow and at what size do their gills disappear? And most importantly, how to avoid further deaths? Is it possible that they were killed by a Blood red jewel cichlid bitten by their gills? The aquarium will have a new 90x50x50cm 225l. And I would have 10x EBJD (3-4cm) with them. Is it possible to have them like this? Won't the EBJD hurt them?
