Okay so I have a 29 gallon tank of 5 black skirt tetras (and 12 ghost shrimp, mind you). They are great, but I am wondering which fish should I have join them because I don't want to add fish that they would kill or attack. I've read horror stories. I would prefer to have fish that would not only get along with the BSTs, but would also add some bright colors (preferably bright reds) to contrast the darkness of my BSKs and gravel. And recommendations to add more BSTs are not what I'm looking for. I do plan on adding a few more. I'm asking about other fish that would be compatible and safe.
