When my 30 Gallon tank is ready for me to add fish after it's cycle, how do I add my fish to the new tank? I was wondering what order I should do it in, like do I only move over a couple of fish at a time over a certain period of time from the 10 Gallon? If so, how long should I wait before I add the next couple of fish? Plus what fish should I transfer first, the Bettas, the Cory Catfish, or the snails? Right now I have in the 10 Gallon tank 4 Female Bettas, 4 Cory Catfish, and 3 snails.
