After having my cichlids in a 55g as a temporary home while I set up the sand in the 75g, I finally moved everyone back to the 75g after it was done cycling, and I did a 60% water change with cooler water to incite the breeding again. They had paired and bred before but I was worried the stress of relocating homes twice would "unpair" them, but looks like it didnt. This is actually the second batch theyve produced successfully, and it was a much bigger count before but natural selection has removed many of them. They are 3 days old and are growing at a fast pace. Enjoy the video! You can see how aggressive mom and dad are
