Congrats on the imbellis spawn! I am lazy with my stiktos and I think I have like one fat fry in there from the dozen or so spawns they have done.
I have had lots of spawning happening here. The one I was most excited about was when my pair of brownorum gave me some fry. I really struggled with this species (seems I am not the only one) and was so relieved when after a year and the sale of my previous pair and purchase of another, I got a spawn.
It also helps that they are incredibly stunning fish.
