I have bred the longfinned abino Bristlenose and the more common brown bristlenose.
Average size for males is around five and a half inches as adult's, with females a tad shorter.
Hard to sex them until close to three inches.
Males will begin to sprout full nose full of bristles at around three inches, and females may also have a few tiny bristles compared to the males, while some females hardly have any.
Males often are larger even when small,and head is a bit broader.(more easily seen as they grow larger).
These fish are omnivore's for the most part, but do appreciate/need some vegetable matter like zuchinni,cucumber,romain lettuce,algae wafer's,lot's of other's. You can google food's for bristlenose.
i feed mive mostly new life spectum which has lot's of fruit,vegetable matter ,and also offer shrimp pellet's,carnivore pellet's,spirulina pellet's.
Have had pair's that spawned as early as three inches,and some that took nearly a year .
Clean water,with moderate flow ,driftwood for rasping on (also help's digestion),more than one cave,log,etc when wishing to breed (let them choose).
Females when about to lay/drop egg's will become much plumper,wider at the hip's so to speak rather quickly, and after they drop egg's , the male will not be seen for a week to ten day's while fanning the egg's. After ten day's or thereabout's,,the tiny fry will have absorbed their egg sac,and begin emerging from the nesting spot but not stray too far for another couple week's.They are voracious feeder's at this time, and vehetable matter ,along with the other food's mentioned, will need to be available near all the time which often lead's to larger more frequent water changes as the fish continue to grow.
Water changes with cooler water often induces spawning, and when fish are large enough to spawn,,twice weekly 50% water changes with cooler water often produces desired result's.
Can remove the female after egg's are dropped to let her rest.
If left with the male ,,they can reproduce about every four week's assuming favorable condition's.
Adult's will show little interest in the fry once the fry migrate away from the nest but the fry make easy snack's for larger fish if they are present.
Did I mention lot's of clean water,water changes? That is the key in my view, along with proper diet.
hope some of this help's.
