I spawned successfully once, it was actually between Helios and a sibling sister! His illness baffles me (I was trying to get some spawn before he passed, don't pass judgement on me lol)... There were only a few fry though, about 20 at most. I moved them to another tank gently and we'll see how they do.
NOW I'm working with his brother Eros and another sibling sister. So far so good! I conditioned them with bloodworms and brine shrimp for 1.5 weeks and when I introduced them to the spawning tank Eros got busy on a bubble nest (after several in his conditioning tank :). I'll keep monitoring the female to determine when I should release her. She hasn't shown barring but she is flaring and swimming alongside him. I have high hopes for this spawn!
The pair:
He use to be much more yellow but the black has been covering him up... same is happening with Helios.
The front girl that's yellow/blue/black
