I have 4 Clown loaches with 6 asst. cory's in a 46 gallon bow and they get along fine. Theres no competion between the two species at feeding and the Clown's spend a lot of there time hiding in the many caves and driftwood pieces i have in the tank. The only fish that bully the Clown's and Cory's at feeding time believe or not are my small Blue Rams who sometimes chase the two away from the algae tablets I drop in a night. Eventually i realize i will have to get a bigger tank but for know everybody is getting along just fine.
