So tonight I went to Wal-Mart and bought three fish which are either koi or comet goldfish. Hard to tell as they were in the same tank and the pictures were hard to fathom, and the perfume lady was the one getting them out for me as the fish lady was at lunch.
I also bought some fish flakes, as opposed to the pellets I had been trying to get my koi to eat with no luck.
I put the new fish into the pond!
Sprinkled some fish flakes into the pond.
All SIX fish, new and old, had a field day with the fish flakes, and it was nice to confirm that the other three were still alive!!
