Morning all. Our new house came with a much smaller pond (3l x 2w x 1d) than my previous ones. I've started with half a dozen shabunks since last summer. In my other ponds they've been great; very visible and happy. This lot are miserable. The water's clean and well-oxygenated, and the food disappears (when nobody's around), but they just hide all the time. If I go out there after dark with a torch I see them best! Their hiding places are few but effective and that's where they'll be. The only scare they've had is the occasional heron dropping by, but so far I haven't lost any. Any suggestions how to make them more sociable. I admit there may be too few fish, but I don't want to crowd the pond with fish all desperate to hide. Thanks
