Platy fish only cost around $2–$4 per fish. Platies are some of the most affordable fish types available on the market, making them a popular choice for beginners and expert fishkeepers alike.
Moreover, platies are easy and cheap to maintain. Fishkeeping beginners can start with just three to five platies, though you can get more if you have the space.
And because they’re tiny, reaching only 2.5 inches when mature, each fish only needs around three gallons of water. A small, 10-gallon tank should suffice for five platy fish.
Lastly, as livebearers, platy fish are easy to breed as long as they’re well taken care of. Even beginners can try breeding them and selling them for a profit!
