Get Wet Ponds And Aquariums is available 24/7 (honestly, call any time) for emergency care.
In an emergency call David directly on 0433 324 347.
He will give you a rough quote and an approximate ETA.
Please note that while everything is done to the best of standards and many of our previous customers have had good outcomes, there can be no guarantees on the emergency cares outcome.
Getting the fish back after being "accidentally flushed" by a brother is not one of David's specialities though.
Maybe try a really good plumber?
