So i got home from vacation today and i look in my 10 gallon and there are 4 Glowlight Tetras swimming in the tank with my Betta. My question is can i up their school to 8-12 and move the Betta to a different tank and can the Tetras be happy in the 10 gallon? Right now the Tetras are lazily swimming around following each other and randomly having a surge of speed. What stock could i do with them because i can't rehome them and tomorrow i am going to my lfs to pick up fish and medicine for my Molly so the quicker the response the better. Thanks in Advance.
