my 33 gallon long has a dense carpet of hairgrass, however i have some Gammarus that have been living inside the grass. Each time i try to catch them, they hide inside the gravel so i cant get to them.
They are eating my grass, and are growing in numbers. Thats why i want to get rid of them.
My tank has cardinal tetras, amano shrimp and cherry shrimps, so i cant throw a cichlid inside to eat the Gammarus.
Does anyone have any ideas how i can get rid of these little guys without having to tear my tank down as i dont want to start over since this tank is looking quite good.
