I'm new in this forum and I'm trying to seek some help because of my terrapin of about 4 years have been biting and pulling out the plastic tube/pipe from the submerged pump, which disallows the filter to work cus it can't pump water up to the filter.
To give you an idea, its an overhead filter. Anyone faced this problem before and have a solution to that?
Just to show you want my RES has done, here's a pic!
