Ranger Pleco
The ranger pleco is a wild-caught species from Peru. These plecos only grow to about one and a half inches and look like they were hit by a shrink machine. Caution, though: the fishermen do not discriminate when they catch these small catfish. Often several babies of other exotic Peruvian plecos, including the grand ranger, are caught and shipped with these fish. We do our best to separate them, but be prepared to have a surprise after a year or two.

Received the ranger pleco and it’s very small, about 1.5 inches. It’s active and seems healthy in my 10-gallon tank. I did notice a few tiny fish that looked different after a few weeks, but I’m not sure if they’re related. Still, it’s a nice addition to the community.

The fish arrived quickly and looks exactly as described. It’s tiny and peaceful. I’m keeping it with other non-aggressive species. I’ll keep an eye out for any new fish appearing over time.

It’s a small fish and hard to spot. I didn’t expect to see another species with it, but I’ve noticed a few small fish that don’t match the ranger pleco. Not sure if it’s a problem or just part of the mix.
