Reliable Construction: The fish feeding cups are made of high-quality acrylic, making them easy to clean. The included suction cups are made of premium silicone, providing a strong grip and ensuring the cups stay firmly in place without easily detaching. Transparent Aquarium Dispenser: This practical, transparent design allows you to easily monitor the amount of food remaining in the cup. This facilitates better portion control during feeding – preventing excess food from stagnating or spreading – which helps prevent water pollution and quality issues, while also contributing to maintaining a clean aquarium substrate over time. Size Details: You will receive a set of two fish feeding dispensers: one round feeding cup and one square cup (ideal for shrimp). Each cup measures 6.5 x 6.5 cm; you can combine them according to your specific needs, and this quantity is sufficient to meet your daily requirements. Easy to Clean: These bowls have smooth surfaces that wash effortlessly. Simply remove any food residue and rinse quickly with water to save time and effort. The suction cups allow you to easily adjust the height of the feeding bowl to suit the size of your aquarium or the specific needs of your fish and shrimp. Multiple Uses: This fish feeding bowl is easy to use and versatile enough to find a place in aquariums, kitchens, or bathrooms. It is ideal for various tasks, such as feeding fish and shrimp, storing soap or small items in the bathroom, or even placing air fresheners in a refrigerator, among other uses.
