I had the fish in a 100gal tank the 4 that died were -12 long the small
ones are 4-8 inches long,1000watt de-icer that kept the water nice at
45c.they didn't move around much because they are in hibernation.They were
in here since October.
==========================
I'm sure if you check there was, or still is a lot of ammonia or nitrite in
the water. That's much to small a pond or tank to keep that many good size
fish in unless your filtration was excessive (huge cycled filter) or you had
a flow-through set-up. They may simply have suffocated.
