Platies are livebearers and can quickly multiply, leading to overpopulation in the tank. Mystery snails, while relatively peaceful creatures, can produce a lot of waste and compete with fish for food. Zebra danios are active fish that need plenty of swimming space.
The minimum recommended tank size for a platy is 15 gallons, and the minimum recommended tank size for a zebra danio is 5 gallons. Mystery snails can be kept in a tank as small as 5 gallons, but they will require more frequent water changes to keep the water quality high.
If you are set on keeping these fish together, you should be prepared to perform frequent water changes and monitor the tank closely for signs of overpopulation or aggression. You may also need to provide additional hiding places for the zebra danios to avoid stress.
Here are some additional tips for keeping fish in a 10-gallon tank:
* Choose fish that are compatible with each other and have similar care requirements.
* Avoid overcrowding the tank. A good rule of thumb is to allow 1 inch of fish per gallon of water.
* Provide plenty of hiding places and plants for your fish to explore and feel secure.
* Keep the water quality high by performing regular water changes and using a filter.
* Feed your fish a high-quality diet and only as much as they can eat in a few minutes.
* Monitor the tank regularly for signs of illness or aggression.
