Hey, y'all! I'm sure that there's several threads on this topic, but I wanted to make mine tank specific. I currently have a 10 gallon tank that's heated and filtered and has live plants. I would really like to add some smaller fish to Bettasaur's tank, but I'm not sure what kind. I really like the look of the tetras. My petco is having a sale where they're 5 for $5. Would they be ok in a 10 gallon as long as I provided lots of hidey holes? I'm hoping this will keep him entertained for times when I'm not at home for a couple days at a time. He tends to bite his tail when he doesn't have any interaction.
Thanks in advance!!!
