I have one female pearl in an established 29g community tank. Every few months I debate whether to get another, perhaps another female, and I always decide that the tank's too small. It may sound silly but I worry she's lonely and would be happier with a "friend" (assuming they'd get along).
She gets along fine with the other fish (cherry barbs, otos, cherry shrimp). I've attached a picture of the setup.
Any thoughts? Thanks and stay safe!
