My male elephant ear betta is in a breeding box in my 20 gal tank. My female betta got in there not too long ago, Tuesday at least, and when i went to feed him, I noticed eggs in the small bubble nest he had built. I have no idea how long the eggs have been in there but his nest is falling apart and the eggs are falling and he's trying to save them. What should I do since he's not rebuilding his nest, and what do I do with the fallen eggs?? My sister saw then mating a few weeks ago and didnt say anything to me about it, so could these be the eggs from then and theyre just dead?
