So today at Petco I fell in love with 2 female bettas, and since I couldn't decide which one I wanted, my dad suggested I put them both in my 5 gallon tank, so I ended up buying those 2 fish. Later that day we went to Petsmart and my dad was upset because he wanted to buy some Albino Catfish and they were sold out. I wanted some catfish for my empty 10 gallon tank. So we ordered 9 of them.
Would I be able to put a catfish (just 1 or 2) in my 5gal tank? OR How many female bettas can I put in a 5gal?
