Frequently Asked Questions

What size tank should I choose for decor purposes?

The ideal aquarium size depends on available space and the visual impact you want. Small 2.5-5 gallon nano tanks work well as desktop conversation pieces. For impressive stand-alone centerpieces, 20-30 gallon medium tanks offer flexibility for creative layouts without occupying too much area.

What types of fish work well in decorator tanks?

Small, colorful schooling fish like tetras, rasboras, and danios move around gracefully to animate decorative aquascapes. Bettas and guppies add pops of color. Goldfish suit pond-style tank themes. Always research species’ needs when stocking decorative tanks.

How often do I need to clean a decorative aquarium?

With proper filtration, lighting, and fish stocking levels, most decorative tanks only need partial water changes around 15-25% every 2-4 weeks. Test water parameters regularly and scrub algae off surfaces during water changes. Fully clean filters monthly.

Should I add live plants to my decorative tank?
