Thanks for your answer,
So this is not either L70 or L76, L265 have more colour of grey and ivory at the pictures both in datz and aqualog but have the same pattern and shape as mine (have not seen them)...they change colour quite often after the mood and therefor I supposed they even look like the L-265.
So this is a species without L-no but have the LDA no 84...to me that only have to compared with photos of these three different L-no they look very similar almost identical to me and now they are four different species

I have to take a closer look on the dentition of my species to be sure they not are a Hypancistrus...I just took a short look before so tomorrow I will pick one up.
They are between 9-12 cm TL and there is a female that are gravide to so I'm hoping they will breed soon.
Are they from the same area of river system around tapajós?
