My new 77gal Brackish tank is in the process of cycling. I'll be moving my 3 Colombian sharks into it in about a week. I was wondering if there are any species of Cory that do well in Brackish water, or any other bottom feeders that are Brackish. I've heard most Cory's don't much like Brackish water, but they'd be the preferred bottom feeders for me. Any suggestions would be greatly appreciated.
