skunk loaches are good in large groups,this makes them more comfortable and reduces aggresion.i would suggest 5-7 skunks and lots of tight hidey hole so they can cram in real snug.this is a favorite habit of skunks.try using root wood as it usualy has lots of crevices and holes.it shouldn't be too much trouble if they chase around each other but keep an eye on them in case they look for new challenges like fish with flowing fins.also make sure that they get enough to eat or they will harass the other fish,so feed kinda heavy but not too much though. you'll figure out how much in a few feedings and don't forget they like a smooth soft substrate.a soft substrate ensures that their barbels won't erode or knick themselves on a sharp rock and gash their undersides.and last but not least don't forget the bifid spines located just behind the eyes on a loach as this spine is painful to be poked by and can puncture bag or get caught in a net.how big is your tank all loaches like a-1 water quality and your loaches could be comprimsed by overstocking.and if it's not too much trouble you may want to put a powerhead or 2 in the tank as loaches come from fast moving waters
