These fish are truley amazing. They can live in almost anything with limited space. Plus they look great in any tank. They get along with almost any type of fish. The only thing, don't put two males together because they will fight until one is dead. But other than that I would recommend this fish because they are low maintinence and add great color to the tank. Another great thing about this fish is that they are fairly cheap, my local pet store usually has them on sale for less than five dollars.
These fish are easy to take care and clean. It's amazing how they can feed off a plant.
