The neon swordtail is a stunning addition to my 20-gallon tank. Its bright colors really pop in the dim lighting. It’s easy to care for and gets along well with my other community fish. I’ve had it for six months and it’s still active and healthy.

I bought this fish for my first aquarium, and it’s been a great choice. The colors are vivid and it’s very calm. I feed it a mix of flakes and live food, and it eats well. Just make sure the tank is not too small.

The neon swordtail is absolutely beautiful. It’s one of the most colorful fish I’ve ever seen. It’s peaceful and doesn’t bother other fish. I keep it with tetras and corydoras, and everything coexists nicely.
