Hello, I'm new on here so I apologize if I'm posting this incorrectly. I just purchased my first tank which is 20 gallons. The fish I originally wanted was neon tetras, 1 bristlenose pleco, and 2 african dwarf frogs but was told that they wouldn't go together well. I really would like african dwarf frogs and would get only them if it meant that they'd be happy. I'd really like some suggestions if possible. Price isn't an issue so I'd be happy to look into anything you recommend. I mainly just don't want aggressive fish such as the betta. Thanks in advance.
