Don't know if this is the right place to post this, if not I apologize. What, if any, other kind of fish can co exist in a Betta bowl with 1 Betta? TIA
I wouldn't put anything in that tank. There isn't very much room that the shrimp can get away from the betta. They will most likely be food for your betta.
Bettas don't get lonely or they need "friends". They prefer to be alone and are solitary so having tank mates will actually annoy them. I thought that too even though I knew but I just say, "If you're happy, I don't mind." :)
