Sudo Starpet External/Hang On Plastic Aquarium Fish Breeding Box Satellite M (new)

This really works well, it works just like a hang-on-back power filter, except that it is driven by an air pump, however you should be aware that it won't work for really tiny fry unless you modify the outlet. The unit comes with 2 different grates for the outlet, the smallest of which has aprox. 1mm slits...big enough for many species of newly hatched fish to slip through. All you would have to do to modify it, however, is to cut a square of fine mesh to fit into the outlet slot. Other than that, I love this Breeding Satellite Box. Nice quality all around, crystal clear plastic for easy viewing, all the components are well built and fit together snugly. It even comes with a valve so you can adjust the air/water flow. It comes with everything you need, except the air pump.The medium is 1.2 liter. If you have room, I'd get the large size which is 2 liters, but the medium is quite spacious and you can raise quite a few fry in it.

The product is quite good actually but all the instructions are japanese although it doesn't take a rocket scientist to figure out how to put it together and you can just follow the pictures. Also, I live in hong kong where this is being posted from and was charged 10USD or 78 Hong Kong dollar for sending it just down the road, i think that this is crazy, as I have posted things here locally many times and postage for such a small item doesn't cost anywhere near that amount, even sending things to the US from here for such a small item doesn't cost that amount.
