Hi

I'm curious to know how big was your bristlenose when he grew his bristles? I'm trying to determine if i have gold nuggets or britlenoses. I was sure it was a gold nugget at first then i was sure it was a bristlenose. Now one looks like a bristle nose and the other 2 look like a gold nuggets. I think the only way to find out will be to see if they grow bristles. They have whiskers but that doesn't deem to have grown.

It may be a female bristlenose.
Some species both sexes have bristles, the males are just larger.

To answer your question, most I have seen develop into males show obvious bristles by about 2 inches.

I agree with Dino. My male was showing larger bristles by about 1.5 inches, and the female, even though she is now "full grown" at approx 4 inches, has very very small bristles

Mine had bristles when I got it, at 1 1/2", and now is 3 inches and just has them around the edges of the head so I still don't know if it's male or female.

My little albino just has teeny bumps and no bristles really.

Mine is about 2 1/2" with small bristles, but I just got him a week ago. He hides in the cave a lot! lol
