if you give a snail a strawberry

It was not a whole strawberry but the part top part cut off where the green leaves are. Though the snails enjoyed it, more than the shrimps.
 
Are strawberries and other fruits bad for the water? How long can they be kept in the tank for? Sorry to hijack the thread :)
 
Most food can be left in for a few hours, as far as I know. Snails eat slow, so you can't do the 15 min thing you do with fish.
 
I actually left it in for a 1 1/2 day :S. Until it looked like that and the snails ate through to the bottom than I took it out.
