The trios consist of 2 females and a male but fry are not a problem, I have a seperate growout tank for them. Also, would I be able to add a small school Harlequin Rasboros? (sp?) Along with another cory or two?
I have a 10 gallon tank that I'm looking to upgrade into a 20 gallon. In my 10 I have a trio of platies, a trio of guppies, and a peppered cory. What else could I add to the 20 to complete it?
