These are regani. They spawn pretty frequently for me, but the fry are a pain to remove since I usually don't notice them until they've started to wander from their parents. I just gather them up whenever I have to do major tank renovations and pull all of the rock out. Once I accidentally turned over a rock and found a new batch of eggs....they were a very pretty shade of green.
The other tank mates are Lemon Jakes, which really don't seem interested in the Julies.
Anyhow, the cichlid stone should make it pretty convenient to remove them this time.
