View Full Version : Got myself a longfin BN pleco by accident; behavior and sexing advice needed.

My original pleco is bulkier and larger bodied but had similiar sized fins so I was wondering what was up; so I did some research and it seems the new guy is a longfin BN. They had it labeled as a bushynose albino pleco; he seems much more docile than my other guy as well. My normal BN will whack my corys or anything that comes near his zucchini with his tail but this guy doesn't.

I don't think it would be a good idea to have 2 6'' plecos rampaging around my planted 29g so I was wondering when I can sex them? The normal BN is about 3 inches the longfin about 2 and a half inches including the tails. Not to mention the bioload being immense with 12 inches of pooping plecos.

I hate the thought of giving one away but seeing how my normal BN acts I couldn't imagine 2 full grown BN in there at the same time though my longfin doesn't exhibit any aggressive behavior. I had adult BN before but never a longfin and never grew them up from babies like this because I always had large cichlids or catfish. Has anyone else noticed the longfins being more docile as well?

tbh the reason the longfin might be more docile than the normal is because it is having difficulties swimming. thats the problem with longfins.... not sure when you can sex them sorry

Thing is, people treat anything bristlenose as the same species. It's not.

Normally you could sex these after about 6 months. 2 males is indeed too much in your tank.

I had the regular guy about 3 months and the longfin maybe 1 both bought as babies; so basicly if I don't see any bristles when I hit the 6 month mark it's safe to say I got a female? That applies for both species I take it.

They really started to grow fast when I got them to eat zucchini for some reason they refuse any other vegetable at least my normal one did and I tried everything. I don't know how I'm going to get zucchini in the winter they don't sell it around here and I tried freezing it but it turns to goop when I defrost it. You would think they wouldn't care if it was zucchini or cucumber but they can tell.

Don't blanche it when you freeze it. I thaw mine and it stays on a fork.

Rub a fresh clove of garlic over another veg and see what that does.

The normal BN has 2 growths on his head I'd imagine that's all I need to know he's a male but ill give it a lil time n see. I'm debating keeping the graceful long fin; they got more in so i could buy 1 or 2 more and take my normal one back. Odds are in my favor to get a male; I really don't like how aggro my normal BN has become some of my corys have fin splits from him!! the thought of him being 6 inches and doing it worries me while my long fin BN are so docile and much better looking tbh.

Getting the normal BN out will be hell I'm thinking put a net down with zuchinni in it and waiting to spring it otherwise I'll have to rip all my tank apart :/

Zucchini in the net at night worked perfect! neat way to get em out easily. I picked up 2 baby longfin albino BN so now I have a sub adult and 2 babies hopefully I got a male between the 3.

Also my sub adult pleco shares the zuchinni and doesn't swat at anyone so my corys feel comfy around it and it even shares with the baby plecos; WAY more docile than the normal BN.
