I am so frustrated with these fish. They are beautiful, and I think cuz they are so pricey and have a short lifespan, I am determined to get fry and grow them out. I have had the pair for ~6 months and they have spawned ~8 times. I was trying to let them raise the fry themselves because I read their parenting was crucial to the survival of the fry. For the first few spawns, they were tankmates with 8 month old angelfish who didn't seem to bother with them spawning, or take any interest in the eggs. The eggs would stay there, on the rock, until they were about to hatch, then they would disappear. All of them.
Some were infertile, some were developing. They never had a huge spawn, maybe 20-50 eggs max. I then took out the angels and gave them the whole tank. They have started to spawn more often, I think. The first time they spawned, tankmate-free, the eggs were eaten (or moved) just disappeared right before hatching. The second time tankmate-free, they ate them the next day. Again, the last time, they ate them overnight.
I know they are fertile, I have hatched one when I had the angels in there by stealing the eggs with a turkey baster and hatching it in a brine shrimp net. I added it with the angelfry I had the same age, and it never made it, I guess. I tried stealing the whole rock and putting it in a net and the eggs succombmed to fungus.
Either way, the parents are not good at removing the unfertilized eggs, and I have never seen wigglers with them, but I have definitely seen 'good' eggs just prior to hatching.
I am so frustrated and want to breed these guys so badly, idk if I should just grab the rock just after they spawn next time and it in methylene blue or what? Try the brine shrimp net thing again with a powerhead blowing softly on them?
I know it's a lot to read, but can someone pls help me?
