Hi! I'm new here. I have a 10 gallon tank I've had for 4-5 months, with 2 betta's inside divided. The betta's have cycled my tank so yes It is cycled. In the future, I was planning to have 1 betta fish with corys. What type of cory should I get and how many? I know they need to be in groups, so I would like to know how many I can have in there comfortably with a betta. Thank You!
