HatchSphere S – a rearing tank for fry

This fry breeder net is for aquarists who need a separate space for newborn fish, either to protect them from adult tankmates or to keep one brood isolated inside the main aquarium. It is a 15 x 15 x 15 cm enclosure that stays in place on the glass without being fixed to the tank structure.

Why it matters

• The walls are made of fine mesh with 1 mm openings, which keeps larger fish out while water still flows freely through the enclosure.
• An internal divider splits the space into two separate segments, so two broods can be kept apart in one unit.
• Suction cups hold the net to the glass, so it can be positioned without tools or additional fittings.
• The top lid allows feeding without removing the net from the tank, which limits disturbance to the fry.

What it works with

The net suits freshwater aquariums where newborn fish need protection from larger tankmates, and it fits the main tank as a nursery or isolation compartment. Its 15 cm cube size suits small to medium setups, and it can be used alongside the standard aquarium equipment already in place.
