9 healthy, well-fed Colomesus asellus. We got these guys to add to our existing shoal, but they've turned out to be a bit more nippy with slow moving fish than our others.
They are excellent snail control and make great, goofy, entertaining occupants in tanks with faster moving tropicals, but I'd keep them away from shy or sedentary species. They do great with plants, too!
I paid more than $20 a piece for these. All 9 for $100 or $15 each separately.
