The flaming fish hoop title may be a little misleading. There are no actual flames but it's fun to see the fish swim through it.
To make this you will need a 3dprinter, the included .stl file and some permanent markers.
1. Print the flaming hoop. Re-size the hoop if your fish is bigger than 2".
2. Color both sides of the hoop with black sharpie. The flames are a mix of red,yellow and orange.
3. Put it in your fish tank and weigh it down with some rocks.
4. Watch your fish risk life and fin swimming through the flaming hoop.
