I have a 60 gallon tank with 1 Small BN pleco. He's about 3.5 inches right now. There's somebody selling a full grown BN on Craigslist and I'm interested in buying it, but I wanted to know if I can have 2 BN plecos in the same tank? My tank is medium planted with rocks and 3 pieces of driftwood. My stock is albino Cory cats, neon tetras, red eye tetras and a small school of serpae tetras.

They can, but its very risky since they are territorial and aggressive with their own species. I would equate it to putting a betta into a 20 gallon community tank. So proceed at your own risk!

Hmm I see, even if they are female and male? I've read that 2 BN plecos can be fine as long as there are enough hiding spots

That's always the case isnt it? lol... There was someone who recently wanted to keep 2 BN plecos in a 75g on the forums recently and I think a lot of people advised against it. Let me see if I can find it.

Its generally if you have 2 males that they get aggressive and territorial with each other. Already having one plus a school of cories, I wouldnt risk it as thats alot of used footprint already with your current bottom dwellers. If its a female you *could* be ok, but its still hard to say.

Hello,

Keeping 2 Plecos of any kind in an aquarium can be hit or miss. I've been fortunate keeping a Bristle Nose and Sail Fin Pleco in my 265g aquarium. Then again, they have so much space in this tank.

Feeding...the Sail Fin Pleco will munch on the top of a zucchini slice while the Bristle Nose munches on the side eating the green skin. Great to watch.

The Sail Fin is 12" long and my Bristle Nose (female) is about 3.5 to 4" long.

Have a back up plan just in case of aggression issues.

Ken

If the other one is a full-grown male, I would not risk it. If it is a female, then could possibly work out. I had my 4 inch male and then got a 5 inch female from another person at the fish club. They are getting along fine in my 36 gallon bowfront. I am hoping for them to breed though we'll see whether that happens.

ETA: I agree about having another tank in case they don't get along. I do have another aquarium if I needed them to be separated.

2 males = problems
1 male + 1 female : thousands of fry
2 females = okay.
Having three tanks with only females !!!

Okay thanks guys. The BN Pleco that I have is a 3.5 inch female I believe. The pleco that I want is a orange full grown BN pleco, they are selling him locally.

Yeah, it has a lot of bristles. Females only have the little "mustache" or sometimes no bristles I believe. But I'm gonna let you guys confirm that as I have a picture of him . Here he is, it's the orange one

I have 5 plecos in my 55, no problems.
its only the second male that brings issues.
They can be okay, but they target each others eggs for food, that usually a breaking point. None of mone have ever inured eqch other though, just competitive.

He is a handsome BOY. I think it is worth a try if you don't mind them having babies. Alison

I don't mind them having babies . I really like that pleco, he looks very nice. You think $15 is a good deal for him?

I wouldnt worry about over breeding either, like some people are saying. Thye bree much less often thencichlids or live bearers.
and not that many eggs either, often my female only lays 10-20 eggs at a time. They can lay up to 200 supposedly, but ive never had it happen.
HOWEVER, males are not very commited and will mate with up to 3 females in one nest! So multiple females may end up producing a load of eggs combined.
