every goddam time my angels eat their eggs, the first 1-2 spawns were great.. but the third spawn had a bunch of eggs and all infertile, they ate it next day, third spawn had lots of egg, last i check was fine, the next day all gone,, is it some thing wrong with the angel or the material they spawned in ( cement slab )?? Or am i doing anyting wrong?? They can spawn twice or 3 times a week.. i fed them frozen blood worms and some other day live tubifex worms... what is wrong?? I have them in a wll established pond, 2 pairs divided by paving in between, about 38.30.28 (l.d.w) they have algae in them, and floating plants, but no broad leaf plants, also some little subtrate gravel.. a pair of gold gold and a pair of marble marble... What abaout your spawns guys?? Should i take the eggs once layed?
