A 10-gallon tank boasts twice the capacity of a 5-gallon setup, thereby housing double the Cherry Shrimp amount. Following the thumb rule of 10 shrimps per gallon, theoretically, you can host up to 100 Cherry Shrimp in such a setup.
However, consider that this is the maximum capacity. As a diligent aquarist, account for maintenance ease, breeding potential, and unexpected population growth while deciding the number. Starting with 40-50 shrimps in a 10-gallon tank might offer you a more manageable and equally vibrant assembly of these crimson invertebrates.
