Do I just leave the pop Bottle there till it's healed or only when feeding is done

I left mine in the tank for a bit doesn't hurt and gives it the chance to heal

i keep my feeding tube in the tank when i feed my acans and i chase off the fish for prob 20 min allowing the corals to completely consume the food. you could also do this if you're willing to deal with the inconvenience.

also make sure your shrimp aren't tearing at it at night. my peppermints got ousted for this very reason.
