i have skunk loaches, too. a school of six that was seven prior to my great tank epidemic. they are hardy, fun, and they frenzy like crazy during feeder time. i think they max. out at 3-4", although mine are about 2", and i've had them for a couple years. i also have heard things about them being mean, but mine certainly are, and when they have those urges they focus on each other. they're very underrated in my opinion.
