Fish maze

thingiverse

I got this idea from my beta testers. The male is chasing the females too much, and they needed more places to hide safely. Since the females are smaller, about half the size, they can retreat into it, but not the bigger guy. Added slots so the light would shine through, making it easy to see where the fish are hiding in the maze. The other side is open, and you simply lean it against the glass. I designed it to be simple to print, with no supports needed. An additional frame was added at the bottom to sink into the gravel smoothly. Depending on the size of your fish, you can scale it up or down easily. This size is perfect for female betas. The dimensions are 100mmX80mmX15mm with entrances 13mm in diameter.
