Take the time out of feeding your fish. Never defrost frozen food yourself again. Feed any type of frozen, flake, or pellet food in 10 seconds or less, dispersing equally throughout your entire tank. Slow Disperse: Disperse food over time (2-4 minutes) to make sure even your smallest fish gets well fed. Quick Feed: Feed your tank in 30 seconds or less. Put the Regulator Cup in, throw some food in, and walk away. Auto Feeder Cups: Food Regulator Cups also available for Auto Feeders, slowly dispersing large pellet and flake food into your powerheads. Removable: Fully removable for cleaning and to keep the natural look of your tank. Easy to Store: Disassemble easily after use to be 1" tall, storing away discretely in your aquarium stand or accessory cabinet Your fish will thank you--select your size of Regulator Cup below, and click "Add to Cart". For all newer Orders (after January 21st 2026) with a Feed Door 5.5" wide (side to side), select the "New" size. For older Orders (before Janusry 21st 2026) with other Feed Door sizes, select the size below which matches your Feed Door width (side to side). *Note: Top Lids Frozen Food Cups are not pristinely clear throughout the cup, like the Top Lids themselves are. Since Top Lids Food Regulator Cups are 3D Printed from PETG, there may be distortions or fluctuations in clarity at certain points of the cup, especially where the cup bends. This is normal. **Note: It is possible for smaller fish (like gobies, wrasse, firefish, etc.) to enter the cup via the holes, and therefore jump out of the Frozen Food Cup and out of the tank even with the Top Lid on. For livestock with this risk, Top Lids recommends placing the Screened Feed Door on top of the Frozen Food Cup so that these smaller fish can't jump out. Top Lids will not in any way be liable for fish that jump out in this way.
