After I open the bag, I put a little of the water garden tub water into the bag with the fish.
Then, I let the bag sink into the water garden tub taking on more water and I coerce the fish to leave the bag.
Here are five of the gold fish in their new home. The other one was hiding under the fountain area. There are several snails in here already and a little hornwort plant which really needs to get growing. A friend who has given me water lilies in the past told me his lilies look kinda stressed this year and aren't as thick so it may be a sparsly planted water garden tub this year.
