our breeding pair of discus always eat their fry. they lay their eggs, let them develop and hatch into wrigglers. as soon as they become free swimming the parents always eat them. any advice will be greatly appreciated.
Waldo said:Have you tried the opposite of what they suggested? Two danios Danios are great cheap dither fish and if they get eaten they make a nice high protien snack. If adults don't have something to protect the fry agains you will notice them spending too much time mouthing the fry afraid of a water mark on the glass that isn't moving. Darken the tank as much as possible. If a rainy season is cause of the spawn then it would be natural for there to be little light in the river.
Fry actually learn how to parent from their parent's It is likely that you purchased this pair from another breeder. That downfall is that if they were pulled from the parents they will be less likely to rear young on their own. You can pull fry however if you do so you risk loosing them or stunting there growth. When they reach the size where you can tell what kind of fish they are (size of a pea) you should think about getting more tanks.
Discus form alpha dominance. you will get some large and some small. Cull the small ones and leave the alphas. They will grow faster and be healthier.
Two words.... Cyclop-eeze. If you don't have some you need it. Great food a bit bigger the BBS. Much healthier, and it's got a lot amino acids to keep everyone healthy. Not a lot is neaded. I've got frozen if you want $30 however it's not the one I would suggest. there is a smaller cheaper bottle that would be your best bet (made for marine fish and reef).
Hope this helps. PS pick up a TFH subscription, if you don't know Jack you need to. "Jack Watley"
