First sorry for not clear question, but thanks for willing to help.
I was in doubt between otocinclus affinis and vittatus, now i check google for huaorani and it seems that it is precisely this kind of oto. Thanks sailedNJ !!
I took a shot and missed :lol: whoops!! If you could get a better shot of the tail like James asked he'll give you a better ID than I can. If anyone would know it'd be James. Any little bit of Oto knowledge I have is attributed to him & his threads & help/advice
They all look so similar
James0816 i am so honored and thrilled to have you here to help me.
We'll i go to grab the camera.:thumbsup:
Thank you very much
