Hey everyone. I have a group of Geo red head Tapajos and 2 of them have paired up but no action. They have been paired up for over a week now. The female anal tube was fully out but still no action. The male bounced around to female to female a couple times. He's now back with the 1st female he paired up with but her anal tube disappeared. They just stay by the rock and chase every other fish that gets near it. Can someone tell me why there hasn't been any action yet? Is it because I'm overstocked? The tank is a standard 90 gallon with overkill filtration with a group of 10 4"-6" Geo Red Heads 70% female/30% males, 3 x Gymnogeo Labiatus 1 male/2 females, and 1 male Leucosticta.
