I bought 2 of those ancistrus but I can't find their true name anywhere. Hopefully someone will be able to identify it.

Piebald

The colour doesn't seem to match. Does this specie have many colour variations?

If needed I can try to take more pictures.

Looks like a close enough match for me.

True, I must have missed that one.

I guess I'll have to see how it grows up for the final identification. I was kind of hopping somebody might have already come across that comercial name.

I'm pretty sure Silurus is right - for two reasons: Silurus is usually right, and it's not an unusual fish (although perhaps one of the less common of the colour variants - certainly albino and brown are very common).

There's no need to wait, Silurus is right.

BTW, for the future (should you have other fish you want to ID) try to make pictures of the fish under water. Colours will look very different when you take the fish out, which makes it harder to identify.

Thanks for the advices,
I'm new in this parts so I don't know the reputation of the people around here. Sorry if I was too sceptical. Frankly what threw me is that I had a response so quick and with so few words.
Thank you Silurus for your prompt help.

Yes, Silurus is often quite brief. He's also a PhD in Ichthyology from University of Michigan, working in Singapore (Raffles Museum of Biodiversity Research), and has described several dozen different species of fish.

But I know, it's not easy to tell who knows a lot and who doesn't in the forum. Just because someone has been a member for a long time, has a lot of posts, or some such, doesn't mean they know a lot - may just be posting a lot!

Yes, this Ancistrus sp. Brown have yet another colour variation....SUPER RED.

they have these in my lfs today under the same name £13 each seems a lot to me for a BN

I think all these different phenotypes are Ancistrus cf. cirrhosus.
I also think "L144" are another A. cf. cirrhosus phenotype. I wasn't sure at first but now there are long fin "L144" so that clinched it for me.
More phenotypes are bound to appear as breeders selectively breed for fixing any mutations that arise which may have some sales appeal.
As a resident algae eater, I think some of these more colorful phenotypes have a place in the hobby as there is no shortage of very similar in appearance but different and valid species of plain brown Ancistrus are being imported.
My only objection is for those breeders who are selling young Ancistrus cf. cirrhosus as "Dwarf Bushy Nose". Only species as small as Ancistrus claro deserve that common name.

The true is to the best of our knowledge NOT a A. cf. cirrhosus.

The "false L144" is likely (some more tests need to be done to confirm) to be a colour form of A. cf. cirrhosus.

Blue eyed, long fin xanthanistic "L144" now exist. Maybe arrived at independently.
A simpler explanation to me is they are merely another phenotype of common Ancistrus cf. cirrhosuus.
Maybe conventional meristics could prove me wrong without resorting to any expensive DNA analysis?
Long fin mutations do come up frequently in highly inbred stocks in many different and popular aquarium species.

My personal opinion will remain that L144 and any mutations ascribed to them are still actually Ancisctrus cf. cirrhosus until I see proof showing otherwise. Many breeders are selling A. cf. cirrhosus as L144 since L144 fetch a higher price than common Ancistrus.

We had this discussion before. True L144 is impossible to get hold of. The ONLY photo in the Cat-eLog is about 15 years old.

The blue/black-eyed xanthic form that you can buy in shops in the US, Europe and anywhere else in the world are all Ancistrus cf. cirrhosus "false L144" (or something else that isn't really what was first given the L-number 144). Long-fin variant is clearly just another variation on the same theme...

And yes, nearly everything bristlenose available on the market (at least of the captive bred ones) is one or another form of the common one.

Here's what been sold to me as Ancistrus "redjewel":

That "Red Jewel BN is different.
What we have seen happen to the common BN Pleco over the years follows an oft repeated pattern of accumulating numbers of selectively bred forms including different colors, normal, long finned and all combinations thereof.
Just like has happened with Angelfish, Discus, Betta splendens, Rams and all the popular species and hybrids of live bearers.
We haven't seen the last of varieties to come.

This looks like the fish(color form) that was incorrectly sold as lda016 a couple of years ago. Maybe the old name did not sell any more.

There is a picture of my ones in this thread.
