Hi catfish,

I've seen this kind of ancistrus before in two german aquariums, lengths from 17-19cm cm.
I honstly don't know what kind of ancistrus this could be, because they look quite familiar with the common bristlenose.
I've heard a lot of theories about these fishes...maybe it is somekind of a mixture of different ancistrus' in european aquariums....or it is somekind of an unknown ancistrus-species.
Sorry, I couln't help much....

With best regards, Anja

Hi,
I think, without daclaration of the exact origin it´s not possible to determine our Ancistrus.
Really big for a "common" Ancistrus cf dolichopterus (but maybe, Marion has also a common Ancistrus with 18cm).
L-43 reaches f.e. a total lenght > 20cm

Hi Walter,

I find only this one page -Ancistrus spp. ""Bussy Pleco" (http://www.aquajapan.com/encyc/catfish/loricariidae/ancistrus/sp0001_e.html), where is Ancistrus similar to female on my picture. But on other pages is L156 about 10-12 cm only. :(

L43 is 20-25 cm, Ancistrus dolichopterus - import from nature - 20 cm and Ancistrus "punctatus" (http://www.planetcatfish.com/ilibrary/loricari/ancistru/147_f.htm) about 25-30 cm, but they are black with little white spots.

Origin of female on my picture is not known.
