Description
Dome Breeding Cone Medium — Mid-size ceramic spawning cone for young discus pairs and angelfish
Angelfish pairs will lay on almost anything upright, from a sword plant leaf to the filter intake, and a clutch on the intake rarely survives. Dome Breeding Cone Medium (SKU: A32M) is the middle size of Nijimi’s ceramic dome breeding cones, a spawning site made to give egg-laying fish a secure, upright surface for their eggs and a sheltered place for the fry to develop. It offers the shape that discus and angelfish look for in the wild, roots and broad leaves at a steep angle, in a material that is simple to clean and can be lifted out with the eggs still attached. The medium size suits young discus pairs, angelfish and other mid-size spawners in standard breeding tanks.
The cone gives a pair a clear choice of site, which keeps clutches off the glass, the heater and the filter where they are hard to protect. Once a pair settles on it, the fish clean the surface for a day or more before laying, then guard and fan the eggs through to hatching. Keepers who hatch eggs artificially can move the cone into a separate container with gentle aeration, while those who let the parents raise the brood simply leave it in place. Because ceramic is heavy and stable, the cone stands upright on a bare floor or on gravel without fixing. Between spawns it is brushed clean in hot water and rinsed, with no soap or household cleaners. In a smaller tank the medium cone leaves more swimming room than the large one.
Usage & Application
When to Use
- Angelfish pairs: An upright site that draws spawns away from leaves and equipment.
- Young discus pairs: A suitable surface for first spawns before fish reach full size.
- Standard breeding tanks: A mid-size cone that leaves swimming room.
- Parent-raised broods: A fixed spot the pair can guard for the whole spawn.
Placement & Care Guide
- Prepare it: Rinse in warm water before it goes in; no detergent.
- Choose a quiet corner: Low flow, away from the filter outlet and heater.
- Give it time: A pair may take days to adopt a new cone.
- Clean after hatching: Brush and rinse in hot water before the next spawn.
