2.5 Gallon Tank

i am against anything smaller than a 5g with fish in it.. i'll maintain my shrimp and snail suggestion.
 
I think I'm going to go hunting a micro heater/filter and use it as an auxilery tank. I don't have any place I could put a fish (aside from a bucket) that would work if something unforseen happens. I have a passion for tiny fish, so I think it'll work for QT.
