Fellow GCCA Member Jason let me know about the Marina Hang-on Holding and Breeding Box, raving about how useful this piece of equipment is for raising baby fish.
In fact, Jason wanted me to test them out so he gave me one. I later acquired another one at the GCCA Holiday Party gift exchange, so I thought it was probably about time I checked it out.
The Marina Box is very much like an air-driven power filter that hangs on the outside of your tank. The construction is good and the material is very clear plastic measuring 9.5 W X 3.5W X 5 deep. I tested the Large size box. On Amazon, this product is about $21. Smaller version are in the $14 range. I believe some wholesales offer them for less.
The product comes with a divider so you can separate some fry or perhaps a smaller adult fish on each side. One nice feature is the offsets on the bottom which allow you to easily adjust the offset of the unit from the tank so that it hangs perpindicular to the side of the tank.
The Greater Chicago Cichlid Association — GCCA — is a not-for-profit, educational organization, chartered in the state of Illinois, dedicated to the advancement and dissemination of information relating to the biology of the fishes in the family Cichlidae, with particular emphasis on maintenance and breeding in captivity. We are simply cichlid hobbyists who love cichlids.
