I have a 22 gallon tank with a male betta and 2 female guppies. I was wanting to get some bottom feeders. Would a Betta be okay with Albino Cories? Also can Cories be kept in a tank with gravel instead of sand?
I'm assuming 22g is a long tank. But get 6 corys for maximum fun & happiness. Small gravel is just ok; it depends on your vacuuming & water changes...gravel can hold more "crap" than say, sand. But cleanliness is more important size of substrate.
