Is a 10 gallon fish tank big enough for 3 baby red ear sliders?

A 10-gallon tank is generally too small for three baby red-eared sliders, as they require more space to grow and thrive. As a rule of thumb, each slider needs at least 10 gallons of water, and they will need additional space as they mature. It's better to provide a larger tank, ideally starting with at least a 40-gallon setup, to accommodate their growth and ensure proper filtration and habitat. Additionally, consider that they will need basking areas and proper lighting, which can be challenging in a smaller tank.
