It allows hobbyists to easily attach and position seaweed or other vegetable foods inside the tank using a strong magnet, keeping the food in place without getting your hands wet. The VeggieMag is suitable for glass or acrylic aquariums up to about 1/2 inch thick. It’s a convenient, hands-free feeding solution for ensuring your herbivorous fish get the nutrition they need.
