Origins: Originally these little rascals came from the Amazon River basin. Supposedly some 50 species cruise the channels and tributaries of this second longest river (some 260 miles shorter than the Nile as Adrian Philp so rudely informed me) in the world. But the albinos more likely came from an Asian fish farm. The ones we sell come from an Iowa breeder.
Appeal: Bristlenose plecos eat algae assiduously. The commoner plecos grow so large, they turn into destructive behemoths. Bristlenosers stay small -- way small – all under six inches. The albinos stay under four inches. And their albino color adds to their appeal.
Size: In a retail tank, you see them at maybe 1.5 inches -- sometimes up to three inches. Theoretically, bristlenosers grow to a massive five inches. Most albinos top out at just over three inches.
Cichlid Tank Mates: Feel free to mix these little guys with North, Central, and South American cichlids. Because of their set of frog stabbers that poke out their cheeks and their tendency to hide during the day, you can probably mix them with African cichlids also. Watch carefully. African cichlids love to eat the eyeballs out of the common plecos.
Foods: Bristlenosers love algae, of course. They also like blanched zucchini and other vegetables. One breeder recommends French-cut green beans. We found a close version of these on special at HyVee three for $1. Another insists that green peas with skins removed are better. Since these little devils can chew into wood, you probably don’t need to peel their peas. We like the frozen ones because 97% of them sink as soon as they thaw. The African cichlids eat the floaters. Most of our plecos ignored the peas. Joe Meade feeds hers spirulina tablets. Bristlenosers also eat sinking pellets, algae wafers, and frozen bloodworms. Go easy on the meaty foods. They do also graze on driftwood.
Plants: Planted tanks work great. These little guys rarely eat or tear up plants. They love exploring your aquascaping and looking for small bits of algae in the greenery. However, I would not trust any plecos with Amazon sword plants. Once your bristlenose runs out of algae he will start scraping the top layer off plant leaves.
Housing/Water: Avoid bright lights. Des Moines water works fine. Nosers seem to like frequent water changes.
Add Wood: Add bogwood or driftwood to their aquarium. It drops the pH, darkens their tank, and gives them something to chew with their raspy dental work. If you put several young bristlenose plecos in a tank you’ll notice them accumulating on and chewing up the wood.
Sexing: Won’t happen on the babies. Both sexes grow bristles. Males grow a larger and occasionally forked crop of bristles. Females grow smaller and fewer bristles. Males also grow a double row of bristles down the middle of their snouts.
Schedule: Nocturnal. Like the shoemaker’s assistants, adults do their main work at night. Young ones also work during the day. You can observe them in action at night with a dim flashlight. A bright flashlight sends them scurrying into hiding places.
Tank Mates: Bristlenose plecos mix very well with all small and medium fishes except their own kind or near relatives. Male bristlenosers like to argue over territories. If you have several, make sure you provide more than one hiding place. They get along fine in a typical community tank as long as they have a hiding place.
Breeding Tips: Evidently PVC tubes grow wild in the Amazon River because the little rascals adapt quite readily to short segments – not pretty but utilitarian. The pair in this tank often hide behind the wood. The watersprite plants growing on the surface help darken this tank.
Breeding Activity: The bristly male takes over the tube he prefers. The female moves in during a brief romantic interlude. After she deposits her orange eggs (on top of the tube’s roof), he takes over and cares for the eggs. Give the eggs five to six days to hatch. Give the larvae another five or six days to absorb their yolk sacs and emerge as small bristle-less versions of their parents.
Fry Care: Once they start free-swimming, feed them microworms and/or newly hatched brine shrimp. As they grow, they seem to like green beans, zucchini, and algae wafers just fine.
Okay thats all that I found about them hope that helps you
