Serious aquarium hobbyists, this simple glass egg tumbler might just save your next batch of precious eggs! Measuring about 92mm long with an 18mm inner diameter, it's perfectly sized for shrimp, small fish, or other aquatic creatures' eggs. The glass construction is inert and safe for your tank environment, and the transparent design lets you monitor egg development easily. The tumbler action helps simulate natural water movement that many eggs need to develop properly, significantly increasing hatch rates. When female shrimp or fish drop their eggs prematurely or you need to separate eggs for protection, this incubator gives them a fighting chance. The installation is straightforward - just place it in your tank with gentle water flow. You get two in the pack, which is perfect for separating different batches or species. Whether you're breeding cherry shrimp, fancy guppies, or other egg-laying aquatic pets, this tool takes the guesswork out of egg care. It's one of those simple but brilliant accessories that serious breeders swear by. The quality is solid, and at this price point, it's absolutely worth trying if you've ever lost a batch of eggs to fungus or other tank mates. Your successful hatch rates will thank you!
