At the moment i have a 2x1x1 with 2 internal filters and 10 ancitrus 4 brown 6 gold, anout 3 male, at 4" and the females are small I want to breed these. Theres loads of wood, pots, tubing and plants in there what do i need to do?
whoa that's too many in a 2x1x1, and too many males in that enclosed space.
Apart from that, other than having the spawning sites, should feed a bit of protein foods to them before you want them to breed, when they look like they will or if you want to give them a trigger (not that you need one it's hard to get them not to breed tbh).
There's so much info on breeding Ancistrus on the site both in the plecos and breeding section... check the search.
