I live with my grandparents, and today my grandma went to petco. They had 5 fish for 5 dollars deal. My grandma got 5 tiger barbs.

When I saw them, I looked online. I see they need a larger space and can be nippers. She said she used to have an aquaruium about 10g and she had a bunch of fish in there back then. She said to put 3 on one side and 2 on the other, I figured it would be too much. I moved Fishy to the 1 gallon I have. Will it be OK to have 5 tiger barbs, 1 female betta, and a frog in the 10 gallon? That's what's there now. Please Help Me, thanks.
