That is what I did moved the parents in their own tank. What is funny I had two mating pair in a 38gal tank with a separator two laid eggs until hatching; went over to the other side the other pair took them as their own kinda cool. I have another tank 38 with 20 1.5 inch small discus. I agree.Sorry to hear that you lost most of the frys. IMHO if you really want to breed these discus, I say go out and get yourself a 20-30 gal tank and put them in for breeding purpose. Once they raise the frys to 4-6 weeks, put the parent back in the planted tank. It's so difficult to breed in a tank with cannister filer, substrates and plants.
Yeah, its true, but that filter I shut off. Everything that happened was unexpected. They almost always eat the eggs and when they hatched I was caught with my pants down so to speak. Sadly I work 14 hours a day and did not have the time to get things set up right. But now I know what to expect so it's all good. Was very exciting to experience though. I have most of the stuff I need for the next time my discus spawn.
That is awesome. They will fan them as long as it takes until they start swimming on their own unless you remove them the fry will eat off the parents, watch out if the parents start fighting. Do you have the equipment and food to feed them when they swim on their own?
