Product Description
- Lightweight.
Unlike other tanks, fiberglass aquaculture tanks are very lightweight. The reinforced fiberglass material makes them less Heavy
than metallic tanks. They are thus very easy to transport and install. You tend to save a lot of money when it comes to
installation costs.2. Completely rustproof.
With the advanced technology used in their creation, don’t expect any rust on fiberglass aquaculture tanks. These tanks are
created from fiberglass strands and high-quality resin to give them the features needed to be rustproof. They also give it a glossy
finish that makes it very appealing. - Strong and durable.
With the right fiberglass fish tank suppliers, everyone should be assured of high-strength and durable aquaculture tanks. They are
known to last longer without undergoing any significant wear and tear. With these features, the tanks should be able to go for
years without any repair or maintenance costs.
Advantage:
1. Our fiberglass fish tanks are both lightweight and extremely durable, made from a tough Fiberglass exterior that is 100% waterproof.
2. Non-corrosive & maintenance-free, requiring only soapy water for normal cleaning.
3. Easily withstands harsh elements without fear of cracking, splitting, or warping.
4. Finish provides a long-lasting, protective finish that is resistant to fading, scratching, chipping, and even intense UV light, for a new or weathered look that maintains its fresh character day after day. Serving life for more than 15 years.

FAQ
Frequently asked questions
What are the advantages of an FRP (fiberglass) fish tank?
FRP is rigid, high-strength, non-toxic, corrosion-proof and UV-stable, with a smooth food-grade gel-coat interior that resists algae and is easy to disinfect — giving decades of service indoors or out.
Can an FRP tank have a viewing window?
Yes — an optional viewing window is popular for display, broodstock observation and live-sales, along with central/side or dual-drain (Cornell-type) outlets for RAS solids removal.
What shapes and sizes are available?
Tanks are molded to order in round, rectangular and D-end shapes from small hatchery/nursery units to large commercial tanks, with diameter, height, colour, fittings and window all customizable.
Can FRP tanks be used to transport live fish?
Yes — the smooth bore suits fish hauling / transport tanks as well as RAS, hatcheries, broodstock, quarantine and indoor intensive farming, in fresh and sea water.
What are FRP aquaculture tanks used for, and where can I buy them?
FRP aquaculture tanks are used in hatcheries, RAS grow-out facilities, indoor intensive farms and live-fish holding systems. A FRP tank for fish farming is preferred where rigidity, smooth hygiene surfaces and long service life matter — unlike tarpaulin tanks, fiberglass aquaculture tanks for sale need no ongoing liner replacement. SIGMA molds FRP fish farming tanks to order in round, rectangular and D-end shapes with centre/side or dual-drain outlets, ready for export to your port.
What does an FRP fish tank cost, and is a used fiberglass tank a good option?
FRP fish tank price is driven mainly by diameter/volume, wall height, drain configuration and whether a viewing window is added — a small hatchery tank costs a fraction of a large RAS grow-out unit. New molded-to-order tanks are the standard offer; used fiberglass aquaculture tanks do circulate second-hand, but check the gel-coat for cracks and UV degradation before buying, since a compromised gel-coat lets algae and bacteria take hold. Contact us for a price quote on a new fiberglass fish tank for sale.
Can an FRP tank be used for fish transport, raceways or troughs?
Yes — the same rigid, smooth-bore FRP construction serves as fiberglass fish hauling and transport tanks for live-haul trucks, fiberglass raceway tanks for flow-through grow-out, and fiberglass troughs for aquaculture nurseries and aquaponics systems. Rectangular and D-end shapes are molded to order for these duty types alongside the standard round tank.
