* Zebrafish need space: Zebrafish are active swimmers and need ample space to move around. A 1.5-gallon tank is simply too small for even a single zebrafish.
* Water quality: A smaller tank makes it harder to maintain good water quality. Zebrafish produce waste, and a small tank can quickly become overcrowded and polluted.
* Stress: Being confined to a cramped space can cause stress and health problems for zebrafish.
Recommended Tank Size:
* For a single zebrafish: A 5-gallon tank is the minimum.
* For a small group (3-5 zebrafish): A 10-gallon tank is better.
Before you get any fish, always research the specific needs of the species and ensure you provide a suitable environment for their health and well-being.
