Hello! I’m setting up my second freshwater tank and plan on housing a single male betta. I’m wondering if and how many corys I can add to a 10 gal? In my 20 gal long I have 6, would ten be too small? Any recommendations for “cleaners” or other friends that can be housed in a 10 gal? I know it will depend on how aggressive the guy is, but just to get the wheels turning! I know for sure I’ll have a single mystery snail. Thank you I’m advance!
