Identify fish for entertainment

I guess the otos are mariae but I didn't look hard, lol.
Yes Maria's Ottocinclus. Only time I've seen that species is when I got those. I also have images of another species and still don't know what to call it. It isn't like anything on planet catfish.
 
I've seen mariae, affinis & vittatus (sp?) most commonly where I've lived. & of course the pretty zebra otos more & more in recent years. Plus a few I can't ID either.

I believe I win the most species identification prize! Do I win all your loaches & otos, lol?
 
Yes you win all of them. There is a caviot though, I don't have any now :D
 
Yeah this is the otto I don't have identification on. Colored a bit like a true sae, tan above dark stripe that extends through the tail and pale below. No spots above the stripe. The most industrious algae eater of all the ottos I've had. Definitely recommend them.
