Overview

The Flexible Round Fish Tank with Metal Frame & PVC Liner by RAINBOW is a modern, portable solution for fish farming and aquaculture. First introduced in 2006, this innovative design combines the strength of galvanized steel with the flexibility and waterproof quality of premium PVC tarpaulin liners, offering fish farmers a practical and durable alternative to traditional earthen ponds.

Unlike fixed ponds, RAINBOW’s flexible fish tanks can be easily installed, relocated, and reused, allowing for multiple rearing cycles throughout the year. This means higher yields, better water control, and greater profitability.

Why Choose a Flexible Round Fish Tank

Conventional concrete or earth ponds are costly, immovable, and time-consuming to build. In contrast, a portable PVC fish tank is fast to set up, requires minimal ground preparation, and can be used in nearly any location. These tanks are ideal for fish hatcheries, backyard fish farming, aquaponics systems, and commercial aquaculture projects.

Key benefits include:

Portability and flexibility: Easy to move or disassemble when needed.
High durability: Built with 32mm or 42mm galvanized steel pipes for corrosion resistance and long life.
Premium PVC liner: Waterproof, UV-resistant, and designed for safe aquatic environments.
Easy installation: No professional labor or heavy machinery required.
Cost-effective: Lower setup and maintenance costs than concrete ponds.
Customizable: Choose size, shape, and capacity according to your space and fish species.
