You can have up to 25 cherry shrimp in a 5-gallon tank. Cherry shrimp are small and produce very little waste, so you can fit a bunch of them in a small tank.
A five-gallon tank is the perfect starting point for cherry shrimp. In general, you can keep two to five cherry shrimp per gallon of water.
If you’re not used to taking care of that many shrimp, you should only start with ten of them. Keeping a colony of ten shrimp can help you get accustomed to caring for them before adding more shrimp to the tank.
Additionally, having ten shrimp in the tank will help them feel safer and more comfortable so that they can behave naturally.
