I really dislike all the confusion regarding Ancistrus, so I now hope for an answer on what is the dominant species of "common Ancistrus" here in Norway, this one is the type you most often see for sale.

Sorry, It'll have to be a link.

[Rusty: Here is the picture:]

Looks like it could be A. triradiatus. Have a better photo? Preferably a mature male with good snout growth.

This is a male A. triradiatus



For comparison A. brevifilis male (bad shot, sorry) Note many short branched tentacles.



And A. sp "Chirgua" male. Note unbranched tentacles.

I have another one of the same species which I am confident is a male, but he has just recently started growing the tentacles, at apx. 6-7 cm length. He is much more shy than the other one, but I'll have a try at getting some good pictures of him.

His colours are quite a bit darker than those of the one in the picture, which I believe to be a female.

Hi König,

it's the same A. sp. commonly breed and sold in Denmark (and for the reader with little knowlegde of Scandinavia - the countrys in Scandinavia share a lot - and the things common in Norway is also common in Denmark (of course there's no rule without exceptions)).
The white dots on juveniles do fade with age, but they will never completely disappear
