@@arefnabulsi96 you must be one of the most uneducated people on earth. It's called fertilizer and the number one fertilizer in the world is fish poop. It's never too late to go back to school and at least maybe then you can make your parents proud
Beautiful setup. Beautiful fish. Clean water. I bet these fish are take care of better then most peoples kids. They probably get the best quality food as well. Well done.
