I managed to get my white clouds to spawn in a leaf litter trough that I was using for skud production. I put them in a few weeks ago and started seeing fry a week later. It is nearly impossible to see more than 2 or 3 fry at a time in the leaf litter so I have been moving them to a 10-gallon nursery tank. It looks like I have about 3 dozen fry of different sizes and ages.
I started with one male and one female, in the trough. A week later I added a second female as she was starting to plump up a bit also.
Shameless plug... The white clouds were my last in-person purchase before COVID 19 from Nova Tropicals.
