, but you need to be aware that they're not all friendly, funny little characters. As wuv mentioned, some of them are aggressive... some of them are very aggressive. Clowns are very friendly in a community tank, but they get massive. Kuhli loaches are adorable, peaceful, and active, provided you get a school of them. They don't get too large, but prefer a sandy substrate so they can burrow into it. The other loaches I keep are in a semi aggressive tank together with a school of tiger barbs and a red tailed black shark. They include yo yo loaches, skunk loaches, and schisturas. The yo yo's are probably the most suited to community life out of these three varieties, but I still don't think they're great community specimens. As juveniles, they're adorable, active, and friendly, but as adults they are territorial and have a bit of a bad habit of rasping on the sides of large, laterally compressed fish (like angels or silver dollars). The skunks and schisturas are extremely nasty little guys, and wouldn't be at all suitable for a community setting. Just make sure you know which kind of loaches you're getting; they're not all alike.
