I bought these platies for my 10-gallon tank and they’ve been thriving for over six months. They’re colorful, active, and don’t stress other fish. The breeding behavior is fascinating to watch.

Easy to care for and very hardy. I noticed the black streaks on their tails after a few weeks. They form nice schools and add a lot of vibrancy to the tank.

Perfect for beginners. I didn’t know much about fish before, but these platies are calm and don’t require much maintenance. They even started spawning after a month.
