I think is a Hypancistrus sp. L129, isn'it?

Thanks in advance.

Sure is!

I am not so sure, L129 and L316 can be very similar and I think yours have to small eyes to be L129.
Any other information like where they are exported from?
Try to take some new pic's with better light and not seams to be stressed.

Hi!

I doubt it is L129. the eye is definitly too small to be L129...

I highly believe they are L316...

I haven`t certain information about his procedence, but not came from Colombia; is the same fish was appeared in this, and previously id as L199:

some more difference between L129 and L316?

Thanks.

They are for sure L316 and I have to admit I was wrong in the other topic and maybe thinking to much between the differents between L199 and L270.
L316 have much smaller eyes then L199 and origin from Rio jari Brasil, L199 origin from the Orinoco tributary in Venezuela but are exported from Colombia.
Both species have a very variable pattern and before the adult size they are very similar except for the size of the eyes.

Thanks Jane.

Then, L129 and L316 only are different in the size of the eye.

Hi!

I agree with Janne, they are L316.
OD: no there is also difference in the overall head shape, but one sure way is to look at the size of the eye

Cheers
