Alright, I am cycling my 10 gallon right now. My plan is to somewhat heavily plant the tank and include a male betta, 2 african dwarf frogs, and I was going to add some corys as bottom feeders. What is the minimum they need for a school? I am kind of clueless when it comes to catfish, so any advice will be appreciated. Also, I am very diligent about keeping the water clean, so frequent water changes are not a problem.
