Had BN's for years in various tanks and they are brilliant characters, so thought in the Juwel 260 which is currently almost empty (handful of platties) i'd have a punt at breeding them.So many an hour was spent looking at the guides and youtube vids - which basically boiled down to a) give them caves, b) give them bogwood, and c) don't overcrowd them, and pretty soon you'll be overrun with babies.So Perfect i thought, i'm not short of tanks for the babies to go into on a more permanent basis, and i went out and brought 3 super reds. I asked for a trio, but the LFS in question is a MA, so skill at gender based sexing is likely to be questionable at best. They are circa 2" long at the moment, but i can see no discernable bristles on any of them.So what age / size should gender begin to become apparent, and what age / size are they likely to begin breeding?Also any particular tips? I'm only planning a single breeding, just for the experience of it and have enough community tanks (i'm a sucker for bargain tanks - please don't judge my addiction!), that if i miss any eggs or fry i can find homes after batch 1 but i'll treat them like Betta's and create an all female group in the Juwel, and a male each into the various other tanks / give away surplus males if i end up being overrun with boys from the first breeding.Any comments suggestions or thoughts?Tony
