Review on Capetsma Fish Breeding Box: Acrylic Isolation & Incubation System for Baby Fish, Shrimp, Clownfish, and Guppies by Julie Bahr

I've used a few other floating breeders and always wish they were bigger. When I stumbled across this one, which showed the actual internal dimensions, I was impressed. I bought it to try and it was excellent. The suction cups hold up well and there are floating handles for backup. The grid on the bottom protects the kids if they fall and the divider leaves enough room for two fish if you're the right size for the right fish. This is the best floating breeder I have ever tried. The only thing I would wish for is a tight lid in case a fish jumps or if the suction cups fail and the cameras tilt and lose air. Both have held up so far, so the non-locking lid wasn't a problem.
