Appearance:
Brown with off white spots, the spots aren't circular or uniform. White on the tips of tail and tips of dorsal fin. There is also an albino common bristlenose that have red eyes and a piebald/calico common.

Compatibility:
A fairly peaceful pleco but will become territorial with other ancistrus if restricted in space or hiding spots.

Sexing and Breeding: Same as other Ancistrus, both males and females can develop bristles round the lip but only males develop bristles up the snout. Males also develop forked bristles but this can sometimes be true for females. Adult females are wider when viewed from above. The common bristlenose should breed without any stimulation but a cave or a suitable place should be provided. Once the eggs are laid the male will guard them until they have hatched, under the males watchful eye, the young will eat their egg sac and will then venture out.

Diet:
An omnivore which should be more towards a veggie based diet with occasional meaty foods. It is also thought that wood should be supplied for Ancistrus species as they may eat lignin which is found in bogwood, this is presumed due to the fact that they have very long guts similar to panaques. They also extract Aufwuchs from the organic layer that develops on the wood over time. This plec is also an ideal algae eater for the aquarium.

Water parameters:
Temp 23-29 PH 6.0-7.8
A minimum tank size of 60 litres for one, wood and hiding spots should be provided

Max Size:
15cms(6")

Bred by:

G'day all
I thought I would add a breeding log of my own..a photo log ...
Here goes..
I had a virgin female bn for well over a year, I usually get them tiny & give them back when they are larger, as I breed rams and other delicate fry, I was initially only keeping them for tank cleaning, But this female I really liked, she had great markings & was a good size. Her new hubby was only about 9 months old, He was nothing special, but I kept this one also once I noticed his bristles growing, Once he had a good number of bristles, I introduced them to each other. fortunately they got on well :D
I left them a week or so to get to know each other...
Sooo......while I waited, I made a cave for them,..
After a week I added their cave..&..
As soon as I placed it in their tank, The female dove right in..lol
I barely got my arm out of the water lol..She was very keen,
Then Mr Bn, skulked about for a while, looking in, then they swapped back and forth, She was in there, then he was in there, then her again and so on, then that afternoon, I noticed she was in there with him..That was fast work lol
This photos with her head poking out is her actually laying her eggs. Amazing stuff & I got to watch the whole romance ..
The parents doing their thang..

I then seen strange behavior from the male, Strange cos this was my first time breeding bns, He was upside down with his mouth outside the cave open to the water, he was sucking a heap..but looked like he was sucking water (I later realised the eggs were just back from the caves entrance, this behavior was him fertilizing the eggs)

He was fanning with his bottom 4 fins. Even outside the cave, seems to be an involuntary thing when they're on eggs ? It looked like he was dancing to a beat lol..
Dad looking very pleased with himself..
