View Full Version : Bristlenose's - Is this normal?

10-08-2011, 05:32 PM
Quite a few months back I bought 3 Bristlenoses all about the same age, same size, just tiny juveniles which I wanted to breed because I've never had Bristlenoses before and wanted to see if I could breed them etc. And I quickly started to notice that one of them was growing much much faster. About a month or two ago he first started getting his "bristles" and he's around 7cm (I'm really bad at estimating but he's big) and the two females are growing much slower, they're literally about 3cm smaller than him.

Is this size difference normal? Will the females have a random growth spurt or just carry on growing slowly? How do I know when the females are mature...?

Welcome to the forum. I'm no breeder but some fish just grow faster than others. From what I've read on AC they reach sexual maturity from 6 months to a year. Try searching, lots of people have bread them. :search:

sounds norml to me. BNs seem to have great disparity in growth rates and even final adult size.
