Fry Saver Box, Nano, 3mm Slots, Suction Mount
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. Inside, the box measures 80mm wide, 55mm front to back, and 70mm tall. Two keyholes in the back wall take your own suction cups. Push a cup head through the round part of the hole, then slide the box down so the stem rides up into the narrow slot. Each keyhole takes a common aquarium suction cup head. Suction cups are not included. Watch your tank after you install it. We print in PETG. Aquarium keepers have used it submerged for years. Rinse before use.

Common questions
Should I pick the 1.5mm slot or the 3mm slot?
Slot width is our own choice, not a tested number. The 1.5mm slot is the narrower option for the smallest fry. The 3mm slot moves more water through the box. Read both sizes and pick what suits the fish you keep.
Should I get the rim hang version or the suction version?
Pick the rim hang version to drop it over the tank wall. Pick the suction version if you want to use your own suction cups instead.
Why is one wall solid while the others are slotted?
The back wall stays solid against the glass. The other three walls and the floor are cut with slots, so water moves through the box.
Does water move through the box on its own?
Yes. The slotted walls and floor let tank water pass through without any extra pump. Water movement comes from the slots, not from an add on part.
