This is a farowella catfish, also known as a twig catfish. They get about 6-7″ long, but have a low bio-load due to being so slender. They eat algae, bio-film, and driftwood, and have a pleasant habit of sitting on top of things instead of hiding under everything like plecos do. A 30 gallon tank should be enough space for them, they aren’t very active, but they do need some open space because they’re very stiff and bad at turning around.
