Id is with out a doubt Ancistrus cf. cirrhosus

[Arlington]

Can anyone id this fellow for me? I'm thinking Ancistrus cf. cirrhosus , but I'm fairly new to plecos. sorry for the poor images. The last one or two are of him stressed from being just placed in the tank so the coloration and pattern is not normal. Any help would be appreciated.

Yes, it's a male Common Ancistrus, Ancistrus cf cirrhosus, apparently of the "Piebald" cultivar.

okay, that's what I was thinking, but could it be L110 or are they the same? Below is a photo from just a few minutes ago and the orange color is gone and he looks all black. Do all commons have a chameleon ability?

Very much doubt it is

L110

Check your fish, are the light spots small on the head and get progressively bigger towards the tail, ending in a complete or near complete band just anterior to the tail fin? If so it's a Common. This young fish shows the typical pattern unusually clearly, and to the best of my knowledge no other Ancistrus is patterned like this.

Do all commons have a chameleon ability?

Yes, they change in brightness and "blotchiness" with mood, but the strong blotchiness your ancistrus showed when stressed still makes me suspect he's at least part Piebald.

Thank you.
