How long should I leave molts in the tank? My shrimp don't seem to eat them often, so they just kinda sit there until I take them out during a water change.
I never take them out, they eventually break down and get taken into the filter or get eatin, not sure but mine always go away after like a week. Because I never suck them up and eventually they disapear. I don't think they hurt anything they aren't meaty or anything so they shouldn't give off ammonia.
That may be why they don't eat them. I made some food for them, and everyone in the tank except the snails loves it, and it has ground egg shells in it. The snails and shrimp are apparently eating any leftover shell bits, because those go away pretty quickly
