I have some breeding calvus, gold ocellatus shellies, and other africans that have eggs but dont seem to take care of them verry well. Either they eat them or something else in the tank does. I was wondering what kinds of contraptions and methods the Monster Fish Keepers use to get eggs hached safely and to raise the fry. Ive heard of egg tumblers and nets that you stick in the tank with the eggs in them. So what methods and devices do you guys use? Opinions would be appreciated.
