1. Triops can get up to 3 inches long depending on the species! Most types are smaller though. 2. You feed them just about anything, I started mine with bacteria and algae, moved up to carrot slices, and when it got big enough to be in the larger aquarium I started feeding sinking fish food. They are omnivores and designed to eat pretty much whatever they can get their tiny hands on. 3. They are not usually used as fish food because their bodies are mostly shell, and many other easier to raise options (like brine shrimp) being much more common. Some people actually tried to grow them as food for people living in harsh environments and remarked that they generally were not very palatable.
@@valerier.2685 they are omnivores so you can feed them anything, but gihg protein+chitin fish food is best so they grow fast. Use shallow tank with large diameter to hatch them, because food drops to the bottom and if the tank is too deep, the larvae can't dive that far down and starve. They eat a lot and grow like crazy, shedding 3x / day. Adults can be 3 inches long and look like little horrors but are actually harmless. If you forget to feed them they'll eat each other though. No wonder they survived for 300 millino years.
