These are so confusing to me! I have 7 of the brown Bristlenoses that look to be three different types.You can't see it on this brown one,but he has a little tip of white edging on his fins.

What about the Albino? I saw that there were at least two different listings on species for those.And here I thought I was safe assuming that there was just one Albino Bristlenose.

I'd say all your Ancistrus are common Ancistrus, ie what Planetcatfish calls Ancistrus sp. 3:

Two females (the brown ones) and a male (the albino), I believe.

I would identify both your brown ones as . If you have any that look different from the two that you'be shown so far, then we'd have to see pictures of those too, as there are literally a few dozen different ancistrus species, and almost all are brown with varying amount of lighter spots.

The amount of white showing on the fins does depend on the age, young ones have more white than older ones.

The albino one is probably the same specie, but I'm not an expert on the albino strain (not that I'm REALLY an expert on the brown ones either, but owning a adult pair and bringing up more than a hundred young ones makes me closer to an expert than some other people... )

Thanks for all your help! By the way,My Albino's just became Parents with over 130 babies! These two pics are of Bristles in another tank.There are three of them.They are all the same dark brown/black marking.No spots or anything.Sorry for poor quality pics-they don't sit still too long.

This last pic is yet another tank.These two came together. I was told that they were wild caught.They are both males,and completely different in colors/markings.It's not a great pic,but these guys hide the most.

It would have been good if you put a label (a number or something) with each picture, as it helps identifying which picture is which fish.

I certainly think none of the last three fish as "common bristlenose" [i.e. Ancistrus sp(3)].

I think the first picture MAY be . As for the others, I suggest you have a look at: http://www.planetcatfish.com/catelog/lo ... thumbs.php

In the last picture, the one on the right looks likw my female. And the second to last looks exactly like a female I have. I have no idea what it is.
