Hypostomus plecostomus otherwise known as sucker fish or armored catfish are those spiny black, bottom sucking, algae eaters found in freshwater aquariums around the world. Originally from South America these nasty exotics have made their way into Texas (and the rest of the South) rivers and creeks through intentional and accidental release.  Where found they are an ecological nightmare.
