A floating fabric mesh box rather than a rigid plastic trap. It hangs in the aquarium and holds a fish apart from the rest of the tank — a pregnant livebearer, a fish recovering from a fight, or a new arrival you want to watch before releasing.
Why mesh rather than plastic — water passes freely through all four walls, so the occupant sits in the same temperature and the same oxygen as the main tank. Rigid traps go stagnant if the flow is not aimed at them.
Specifications — approx. 16.5 × 12.7 × 12.7 cm. Fine mesh.
A limit worth knowing — a mesh net does not separate fry from the mother the way a V-bottomed trap does. If you are breeding livebearers and want to save the fry, the Guppy Breeding Tank 3 in 1 or the 2 in 1 Fish Hatchery is the right tool.
