Buying Guide
What size fits your space? Choose capacity based on available surface area and whether you plan to keep one or two small fish. For desk use, 2–3 gallons balances visibility with manageable maintenance.
Material matters. Glass offers clarity and scratch resistance; high-quality plastic is lighter and less fragile but may scratch easier. Rimless designs provide an open view but require careful placement to avoid accidental knocks.
What’s included? Some kits add filters, LED lighting, or separators. If you want quick setup, look for a kit that includes essential equipment and a lid to reduce evaporation and jump risks.
Maintenance needs. Smaller tanks require more frequent water changes and careful monitoring of ammonia and nitrite levels. Consider a tank with a simple filtration system or a water-change schedule that fits your routine.
Decor and viewing. For best viewing angles, prefer tanks with clear walls and stable stands. A design with a mat or non-slip base helps prevent movement on desks.
