I was happy when I learned how to make the DIY filters w/a coke bottle and a bubbler, unfortunately, I think I might have put it together wrong
I set this up in one of my shrimp tanks and I have found several shrimp lodged in the contraption, growing.
One of the shrimp are upside down and stuck to the point where it can only move its arms, in the picture, it has grown to that size
Is there a trick to keep this from happening again? Im using sponges, maybe if I use gravel then this wont happen?
