Yep, Farlowella.
In brief, these need relatively cool, very well oxygenated conditions. They are almost entirely aufwuchs feeders and won't compete with other plecs or catfish at feeding time. You will need to give them either lots of green algae or a suitable substitute, such as algae wafers. They should be the sole bottom feeders!
They are targets for bullying or nipping fish, and if harassed, stop feeding. Most specimens either die from starvation or heat exhaustion, so those are the two issues to bear mind.
They are gregarious, so keep in schools of 6+ specimens.
