Fry Saver Box, Standard, 3mm Slots, Rim Hang

This is an open top box that holds small fish apart from the rest of the tank. It prints as one piece, so there is nothing to put together. The left wall, the right wall, the front wall, and the floor are all cut with slots, so water moves through the box. The back wall is solid, because it faces the glass. The slots measure 3mm. That width is our own choice and we have not tested it against any fish, so look at it yourself and decide whether it suits what you keep. Inside, the box measures 120mm wide, 80mm front to back, and 100mm tall. A channel on the back drops over your tank wall. It opens to about 10.8mm, and a nylon thumb screw takes up the slack on a thinner wall. That is an adjustable range, not a fit for any one tank, so measure your own wall first. Nylon will not scratch glass. The thumb screw is not included. No box is a substitute for watching your tank. We print in PETG. Aquarium keepers have used it submerged for years. Rinse before use.

Slot width is a new choice on our end. Check the fit before you trust it with livestock you care about.
