Breeding

[Sesshis_grl]

Ok I thought my angels were trying to breed but I'm not seeing anything! I still see breeding tubes but there is little to no aggression anymore. And they have not paired off to do their own thing...everyone just schools together. I saw my yellow one messing with the heater and I thought she was cleaning it to prepare to lay eggs ( I know this isn't good but I'm not set on keeping the eggs) but nothing.

How long does it take for them to get to the point of laying/fertilizing?
