can anyone give me info on breeding bn

OH TOLEEDY!

Use a minimum of a 25 gallon or 20 long. Have a good few caves, and also have a piece of pvc pipe stuck in the sand or gravel on an angle. All this will provide a spwaning cave and territory. I would'nt have any other fish in with them thou. The male has a more bushy nose compared to the female. And the parents will care for the fry aswell.

You must have a piece of PVC pipe & a piece of Driftwood. The male will find a hiding place & the female will follow him occationatly. The female will lay yellowish/orange eggs & the male will guard them. It takes 4/5 days & the small fry will eat the egg yolk. Later on feed them finly chopped lettuce & cucumber & crushed Algae wafers.

I have found that none of my ancistrus breeders will use pvc. Rather, they prefer slate and other narrow crevices in which the male will jam himself in to. Bamboo also works moderately well. Current should face into the spawning site. Temperature is maintained at around 80 F; no less.

Bristlenose plecostomus are perhaps the easiest plecostomus to breed in an aquarium. When sexually mature, a male will find a suitable spawning location and claim it as his territory. This may be around or under a hunk of driftwood or inside or under PVC pipe or clay pots. He will defend the spot from other males if present. To promote spawning, Baensch's aquarium atlas suggests doing a 75% water change in November (in the Northern hemisphere). The shorter days of winter and the water change make the plecos think it is the start of the rainy season. If the tank has a female(s), she will enter his territory and spawning site when she is ready to lay eggs. Eggs are stuck on hard surfaces, on top, hanging from the "ceiling." The camouflaged male will guard the orange or amber eggs until they hatch about ten days later. After absorbing their yolk over three to four days, the tiny, baby plecos will immediately start to work on sucking algae off of surfaces. If there are other fish in the tank aside from the plecos, the babies or eggs can be moved to another tank to prevent those fish from eating the babies. Some breeders remove whatever the eggs are laid on into another tank and give the father a replacement site (wood, pot, PVC, etc.) to guard. Although I have not bred these fish, I would think it would be better to keep the eggs with the father so that he can aerate them and tend to them. The babies can be removed after hatching.

One aquarist reports that bristlenoses will breed in deep, narrow caves like hollowed-out driftwood or PVC pipes that are about 1.5 inches diameter and about 6 inches deep. They use soft and slightly acidic water. Their babies emerge after almost two weeks. Females laid about 50-80 eggs each time.

According to a few aquarists, their bristlenoses will breed at one year old. Mine is at least one year old though (8/02), and he is not near the 3 inch plus length of most breeders. I say he but I think she is female and still under 2 inches long.
