Marina Betta Ornament, Granite Wave

Marina builds its betta ornaments around a real problem: betta fins tear easily, so this granite-look piece is moulded with smooth, rounded surfaces instead of the hard edges found on ordinary aquarium decor.

Key features

• Smooth finish that is kinder to long, trailing fins than typical moulded plastic or resin decor
• Stone-look styling for a simple, natural-looking small tank
• Non-toxic and fade-resistant, made to keep its colour under aquarium lighting
• Scaled for nano and desktop aquariums rather than large display tanks

One of six designs in the Marina betta range. A betta still needs heated, filtered water and an unobstructed path to the surface, since it breathes air as well as using its gills, so keep open swimming space above any decor. More from the brand in Marina.
