These are designed and formed around reusable/replaceable feeding cups, just fill with fruitfly media, banana, or even gecko food.
Without the top piece on it keeps all the dusted flys in one spot that is easily accessible for darts or geckos so you can insure they’re getting all of their vitamins. I even use one in my mourning gecko setup where she can go down to eat her gecko diet and the flys are already there feeding on it aswell
Using the mesh cover I designed it gives flys a space to breed and lay while a keeper may be out of town, like leaving a banana in the enclosure but cleaner, allowing the flys to produce larvae in the dish and keep hatching flys while someone is away. ALSO can be used to gut load frogs who have trouble eating, fill the bowl with larvae active media and allow them to eat, or pull the top of for ones that have already produced inside!
I will say these are also great for making frogs more bold, so far ever viv we’ve tested in all the frogs now wait perched for food.
I’ll post all my dart product and ideas here and updates on my page Awzy Prints
