These Mipcase feeder clips are such a simple but brilliant solution for feeding veggies to your aquarium fish. You get 8 transparent suction cup clips in the set, which is plenty for multiple tanks or having spares on hand. Each clip has a suction cup that's about 1.6 inches in diameter - they stick really well to glass surfaces when you prep them properly (pro tip: soak in water for 30 minutes before first use for best adhesion). I've used these for holding everything from dried seaweed sheets to fresh lettuce and zucchini slices for my herbivorous fish. The plastic material is safe for aquarium use and holds up well underwater without deteriorating. What's great is you can position them at any depth in your tank, so whether you have bottom feeders or mid-water species, everyone gets access to the food. The design keeps the vegetables secured in place so they don't just float around and mess up your water quality. My plecos and tangs absolutely love being able to graze naturally on the clipped veggies instead of having food scattered everywhere. The clips are easy to move around when you want to change feeding spots or clean the tank. They're one of those accessories you didn't know you needed until you try them, and then you wonder how you managed without them. Perfect for community tanks with vegetarian fish that need their greens!
