Dave+Amy Posted October 8, 2008 Report Share Posted October 8, 2008 How big do GBAs have to reach before they're a good size for breeding? Also - are they usually territorial? I have 5 GBAs in my 6' tank and the biggest male seem to be REALLY territorial - chasing every other GBA. I've noticed HUGE chunks of tails being biten out - is there too many GBAs in my tank?

firenzenz Posted October 8, 2008 Report Share Posted October 8, 2008 Have you a cave for dominant male? he wiil defend that rather than whole tank. I would think you have enough room provided you have hiding options. Otherwise take out subordinate males. Breeding size about 7cm. Quote Link to comment Share on other sites More sharing options...
Guest Posted October 8, 2008 Report Share Posted October 8, 2008 I've seen breeding pairs of BNs that are only about 6cms but I'd say the best size to breed them would be 8cms + but they may start breeding at a smaller size than that.

Dave+Amy Posted October 9, 2008 Author Report Share Posted October 9, 2008 I've provided caves, driftwood with big gaps etc for them to hide - he doesn't seem interested in the cave at all...he's too busy chasing others from which ever plane of the glass he's on, the dominant male's around the 8/9cm mark and the others range from 4-6cm (but these aren't sexable yet) - the dominant male has the largest chunk out of all the tails missing, the smaller ones only have slight tears.

Dave+Amy Posted October 9, 2008 Author Report Share Posted October 9, 2008 I've run out of tanks there's an even grumpier + bigger normal/brown male bristlenose in my smaller tank, he got added to the larger tank because he and the other used to fight ALL the time :roll: Quote Link to comment Share on other sites More sharing options...
lmsmith Posted October 9, 2008 Report Share Posted October 9, 2008 Maybe they need more caves, or caves that are more suitable. How many females do you have? If you have say, 4 males and only 1 girl, I could see there being some problems. Quote Link to comment Share on other sites More sharing options...
Caryl Posted October 9, 2008 Report Share Posted October 9, 2008 This is interesting as I have never had a problem with any of my BNs (plain browns) fighting and I have 5 adult males and 2 females in a 250L tank (plus fry) Quote Link to comment Share on other sites More sharing options...
lmsmith Posted October 9, 2008 Report Share Posted October 9, 2008 I've got 3 males in with 1 female at the moment, and I've noticed the boys are lots more aggressive than they usually are (when they're in a tank with 2 boys and 3 girls). Maybe it's just my fish! Quote Link to comment Share on other sites More sharing options...
Dave+Amy Posted October 9, 2008 Author Report Share Posted October 9, 2008 at this moment can only be definate there is one boy and one girl - the rest are still unsexable (5cm including tail), but I definately cant put my boy GBA into the same tank as the brown bristlenose (both boys and same size 9cm), the brown one gives it a good beating that's for sure. could it be that my male is frustrated?? since the only girl avoids him and the rest are too young?
