Is there a posting that teaches you how to look up and ID a fish?

[Viktor Jarikov]

Welcome to the Planet!

IDK about the bottom fish but the others are a common plecostomus catfish and a Pimelodus pictus catfish.

Browse Cat-eLog and familiarize yourself with catfish families and genus and find your favorite species for starters, e.g., here is the pictus: https://www.planetcatfish.com/common/sp ... ies_id=276

For your larger pleco, it's definitely a Pterygoplichthys of some kind. From the photos, I can't tell between

Pterygoplichthys disjunctivus

and

Pterygoplichthys joselimaianus

. From the underbelly, I'm leaning towards P. disjunctivus because of the scrolling pattern. From the side view, I'm leaning towards P. joselimaianus because of the pale spots on the head and body with what appears to be a dark background color. A better photo of the whole body from a side view with dorsal fin flared would be helpful.

And yes, for the other,

Pimelodus pictus

.
