register your fly! we regularly check the records almost daily so dont worry! but there are necessary steps if ur fly is injured 1. if a yellow-greenish thing is coming out, it's the fly form of blood, hemolymph. immediately wet a paper towel and cover the area to act as gauze 2. take good care of your fly and check for any symptoms of distress, like maybe being aggresive, not eating, pooping or drinking. 3. if your fly doesnt react to basic stimuli like light or touch, it is probably dead. prepare a basic resting place by wrapping it in paper, then bury it. we r not sure if u should give it to a carnivorous plant. 4. if your fly is drowning, take a buoyant tiny item and make a DIY "lifebuoy" for it. it is recommended you DO NOT touch it with your bare hands. as the ticklish feeling might make you respond to a panic response and drop the fly. it is also unhygienic
