My filter has just packed up!

How do I save my fish at this time of night?

What size of filter and what type of fish? If you have an airstone and pump then that will be ok overnight for them. If not then do a 50% water change if its a smallish tank or 25% if its big and that should do them until tomorrow if your tank isnt overstocked.
