We were sold a Hillstream Loach under the name of a Borneo Emperor Loach several months ago. The LFS wasn't incredibly helpful, aside from saying that they wouldn't get too big. We took the wee guy home, and he was dead within a week. As they weren't terribly cheap, I wasn't keen on trying another one, but my husband insisted, and I'm glad he did. The second guy has gone down a storm so far. We keep him in a community tank that's set about about 75F, with some guppies, neons, coolies, a cory, and a betta. We've placed a chunk of bog wood, a trunk-like ornament with fake plants attached, and a decent sized air disc in, and Suki the loach has prospered, and dare I say one of the best algae eaters we've got between our tanks (he seems to love licking the algae that gathers on the fake plants!).
One question, if anyone knows...since they like colder water, would these guys be any good in a Goldfish/coldwater tank? My dad's always looking for bottom/algae feeders, and I think he'd get a kick out of one, if it could survive.
