Marina Multi-Breeder 5-Way Trap

A breeding chamber that clips to the side of the tank, with a divider so two expectant females can be held apart and lower compartments that catch the fry out of reach.

Key features

• Attaches to the tank wall instead of floating loose, so it stays where you put it and will not drift under the filter outflow.
• The centre divider lets you hold two gravid females at the same time without them harassing each other.
• Segregated lower compartments collect falling fry, which is the whole point — it is what keeps a hungry mother from eating them.
• Doubles as an isolation chamber for a sick or weak fish you want to watch closely for a few days.

Keep the stays short. A small chamber is a stressful place for an adult fish, so release the female once she has finished and grow the fry on in a proper tank as soon as they are large enough to be safe in it. For soft-sided net enclosures and other approaches, see Breeders.
