My fish have suddenly hidden themselves after swimming around for months on end. I've spotted some of them briefly so we haven't been cleaned out by a heron. Some may have gone ,however. Any views on what has happened, please
Heron ate most of mine but some were able to hide. Do you have a cat or a dog? Next door's dog ate all his koi, scopped them out and swallowed them, vey expensive loss!
Sound like a heron has visited and had some and the rest are keeping well out of the way in case it comes back for seconds. Maybe a net over the pond will deter it.
i thought my fish had disappeared one spring, They didnt come up for food I put out for them,then came to the conclusion they were not hungry as they were feeding off the tadpoles that had spawned.Maybe this is the case with yours.
