The latest fishkeeping products tried and tested, including the Ziss GL-1 Fish & Shrimp separator, Northfin fish food, Sicce Syncra SDC 7.0 pump. Plus new product news.
I’ve tried countless types of breeding traps during my fishkeeping career – from floating double-bottoms and hanging nets to external hang-on breeder boxes and V-bottom traps – but the problem with many of those is the size.
A tiny plastic cage is not the calming environment an expecting livebearer mum deserves, especially for my Panda guppies.
So I was intrigued by, and keen to try, the ZISS EZ GL-1 Fish & Shrimp Separating Box at the AQUA Telford show.
It’s aimed at livebearers and the first thing that struck me was that the whole kit feels solid, with quality plastic used, and the design is contemporary, with plenty of practical features.
For a start, the flexible mounting system, which comes with both a hanger and a suction holder, gives you an opportunity to use it in almost every tank. A further useful feature is the removable fine bottom mesh, which allows you to use the box either as a standalone breeding trap, where the newborns remain within the box, or as a breeding unit, where the babies can swim out to the tank below and only the female stays.
The GL-1 has its own brilliant aeration and water circulation system (you need to connect it to an air pump, though), which sucks water through the centre column from the tank below and then spreads it over the box. The water then leaves through the mesh bottom.
This water flow creates suction at the four funnelshaped traps, quickly moving the newborns down to safety. The same flow helps you to get food to the fry in the holding chamber, which is extremely useful when you have multiple pregnant females in the box and you must feed the firstborns.
If you want to access the juveniles in the holding chamber, you have two choices: the first option is to open down the bottom of the breeding box and let the youngsters to swim out; the second is to lift the funnel trap unit. The issue is that disconnecting and then reattaching the airline, which runs through the middle, is more complicated than I first anticipated. However, this is the only negative I could find with the box.
After removing the trap, you can use the ZISS GL-1 separation box as a nursery, an isolation chamber or even as a makeshift photo-box. Reviewed by Gabor Hovarth
