While often temporary, pond fish tend to "hide" for a few different reasons. Given time and small adjustments to your fish will show themselves again! First step is to determine the most likely reason your fish may be hiding:
Are the fish new to the pond?
Adding new fish to you pond could cause your existing koi or goldfish to hide too. You can try to coax your pond fish out from hiding by being consistent: feed the fish at the same place and time every day, ensuring that your shadow is not casting itself over the pond. They need to learn to trust you!
Have there been any changes in water quality?
As temperature rises during the summer, the need for dissolved oxygen in the hot summer also increases. If ample oxygen is not available, the health of the fish can be compromised, stressing them out-- oxygen is especially important as your fish grow. A great way to dramatically increase the aeration is by the addition of a air station, also known as a bubbler.
Bubblers can be used on the bottom of the pond during the summer and on the plant shelf during the Winter to maintain a hole in the ice. Dreamscapes sells air stations (bubblers) in their Retail Aquatic Center year round!
Have there been any recent visits from predators?
In order to keep heron out of your pond, you can try a combination of different measures:
1) String fishing line 1-2 inches apart laterally across the pond in areas where plant shelves exist. The fishing line, if strung correctly, deters the heron by making it difficult for them to step into the pond.
2) Use a "Heron Decoy" by Aquascape, Inc. making sure to move the decoy every other day when you know the heron is lurking. Heron are very territorial birds and they do not like to share with others. They are also smart birds and they will know the decoy is a fake if they realize it has not moved in some time.
3) The use of a pond net, though unappealing, protects the fish by making it absolutely impossible to get into the pond. This could be the same net you use during Fall/Winter Pond Maintenance.
These are a few of the more common reasons and solutions to you koi fish always hiding. It’s important to remember that most of these issues can be resolved and given time, most fish will become comfortable in their home and show themselves more frequently.
