Aquarium Breeder Box

Aquarium Breeding Box with air driven water flow. This box floats in an aquarium to house newborn fry and wigglers to begin growing them out. The float "arms" are attached to the side of the box after printing to keep everything printable without supports. I used aquarium safe silicon seal like this: https://smile.amazon.com/dp/B0002BBX3U/?coliid=I2MKEYZ8VA025Q&colid=2FJ5TKJV32QDJ&psc=1&ref_=lv_ov_lig_dp_it After adhering the float arms, a couple of pieces of foam are attached under them as floats. Pieces about 20x25mm work fine and you can adjust how deep in the water the box floats by adjusting the size of the foam you use. You can get closed cell foam everywhere, big box stores like Home Depot, Lowes or WalMart. Even craft stores have it. An air tube fits in the socket at the back of the box. Adjust airflow to give whatever amount of water flow you desire. The end filter is cut from scrubber pads available everywhere. Dollar stores, Walmart, etc. The scrubber pads are 180mm x 85mm and I made the boxes take either an entire pad (large box) or half a pad (small box). I find the small boxes work best for me as I spawn dwarf Corydora catfish and Blue Rams and after they are in the box and free swimming, they don't stay long before moving to a grow-out aquarium.
