Clown loaches don't want to be a community fish. They really like to have alot of space to themselves in the bottom of the tank. They prefer to live with other clown loaches. The larger the group of clown loaches the better. (In their natural environment they'll shoal with hundreds and even thousands of clowns.) Only having 2 is obviosly causing problems. They need plenty of hiding places where they won't be bothered at all from other fish because they need their 8 hours of sleep per day. They prefer a low light environment and the water temp to be around 80F. They love to eat more than anything else, but they need a variety of foods.
Perhaps you should sell the clowns back to the LFS, they'll easily outgrow your tank in a few years if you can keep them that long.
Clown loaches can adapt to almost any tank condition, but it doesn't mean they'll be happy. To me, clown loaches arn't fish, they're family. I have 2 tanks that are dedicated to them.
