You should tell your mom that if he doesn't get friends he will get sick and die. He may seem fine but most problems lie below the surface.
But you really MUST get a bigger tank for them.
Ideally you should have at least five tetras, three upside down catfish, and five cories. Anything less than that and you will eventually have issues.
