Stippled Clingfish?

Anyone know much about these? They look like little plecos, though they unfortunately seem to be carnivores instead of awesome algae grazers. I saw a source saying they wag their tails when happy and they are tank bred which leads me to believe they are a lot easier to keep than a yellow stripe. My friend is considering one but there doesn't seem to be many people claiming to have had one out there.

 

Carnivore. In the wild, it feeds primarily on benthic crustaceans (amphiopods, isopods, small shrimp and crabs) as well as worms and small fish.

 

Although their shape is suggestive of the Plecostomus or sucker-mouth catfish popular in the freshwater aquarium world, clingfishes are carnivorous and members of the Family Gobiesocidae—goby-like fishes with a suction disk on their ventral side formed by fused pelvic fins. This is not the mouth, as some mistakenly believe.

That is one ugly fish ...

 

Thanks for the link. Seems to be an easy fish to keep. I think it's cute, especially if it wags its tail. From above it kind of reminds me of a horseshoe crab.
