Egg mass found on sand bed. I disposed of the egg mass but wish I had put them in a tumbler and at least tried to hatch them.... However, I feel confident that they will spawn again soon

Awesome Doni. So, how did you determine male from female; and how did you get them paired up?

Fantastic! I've seen the spawning display but have never had eggs (and lost the female soon after).

Any update on these guys? How long after you noticed flashing did they spawn? My male has started flashing but the female seems to ignore him so far.
