I bought the pair from the same tank at the LFS. They were the only two marble with 6 other black lace's. They have grown considerably since I got them. I did/do not know if they are a mated pair and if the eggs are fertilized (will Angels lay eggs if there's no male?)
They were always very friendly in the community, but now they a guarding these white specs very aggressively. They seem to hover about them as though they're fanning the eggs.
I've had more than my share of live bearers, but this is new to me so some research is required.
