Is this a bristlenose?!
1 Attachment(s)
Here's a photo of a Pleco I just bought. In the store they were calling him a Bristlenose pleco. The only thing is... he has no bristles!

Is he just a juvenile that will later develop the characteristic bristles?

And while we're at it, what behavior is typical of bristlenoses? I can't tell if he's adjusting well to his new tank.

I have to say I don't think so, because of the polka dot looking spots (mine has more like smudges) but sometimes the juveniles are more clearly marked. Does it have bristles? It could be either bristlenose or bushynose.

the only sure-fire way is to wait and see if it grows bristles. But maybe the more experienced people here can help identify through body shape. There could be subtle differences that I missed.

Bristlenoses, actually most plecos, can be quite shy when new. if you see him going out more, then I guess it's a good sign.

it looks just like my BN, both bristle and bushy nose are the same thing just called different names. my youngest hasnt started getting bristles yet...if it is a likely wont develope them at all....was it sold to you as a BN??

It certainly looks a lot like my BN, who has just started to get his bristles. They LOVE bogwood, and mine spends much of his time sucking on that, or on his algae wafers! He also likes to 'suck' his way around the tank looking for any algae growth. He is very peaceful and great fun to watch, though he can get a little possessive over his wafers! :)

Haha, thanks everyone! :)

Well, he seems perfectly happy now, he sucks around on the glass and on the driftwood piece I put in there. I just found out I have to return him, though. My tank's not big enough for him, contrary to what the pet shop people told me. :( I'll miss him. He's so adorable.

It is a bristlenose. Ancistrus sp. 3 to be exact.

Surely a 55 gal is big enough for him?

adiumroot 01-14-2010 11:39 AM

Yes. A 55 gal is more than enough. Bristlenose plecos grow to only about 4 or 5 inches, with 6 inches being a big specimen.

What is the minimum tank size for a BN?
