My tank was recently taken over by velvet, and being somewhat of a beginner, I ended up not realizin it until it was too late. Now that i have no fish, I'm starting over. I'm working on getting my tank up and running again, and i'm thinking i want rosy barbs. My tank is a 10 gallon tank. Can anyone tell me if they would be ok in there? And if so, about how many should i get? Any help/ideas is greatly appreciated
