severum mama said:Those are Synodontis cats. I have quite limited experience with them so cannot name the species off the top of my head. Also, there are some Syno hybrids that are commonly available in the hobby so that makes it a little more difficult.

*edited to add* There are many species of Ancistrus plecos available in the hobby. Be sure to check out plenty of pics within the genus!
