130+ eggs were pulled from 8 adults in a 40 gallon breeder with some Ancistrus sp. and Apistogramma caucatoides growing out. I did a 50%+ water change a few degrees cooler two days ago and have been feeding live black worms and high protein pellets.
They laid the eggs in the evening on the glass and under anubias leaves. There was a larger ceramic media rock she kept trying to place eggs under to no avail.
Also included in video/pictures are three fry that hatched on Feb. 1. You can see they haven't developed the dark face and bold orange yet, but they do have the gold iridescent sheen on their cheeks. Their bodies are a pretty light orange color.
