A funny story for you..
So I have 3 little container ponds in my yard, two about 25 gallons and 1 60 gallons. With guppies lillies and other small fish in them.
I changed the water on them last week and topped them up well given the recent heat.
When I came home today with the rain I noticed that they were getting quite full, but since it stopped didn't worry about it.
Of course the storm restarted a couple hours ago and the rain has been heavy. So I look outside and two of the ponds are about ready to overflow. Now with koi or larger fish, a lite overflow isn'tan issue but with small ones they may be gone before they know it.
. Out into the thunderstorm I go, with bucket, hose and net to catch any fish I might accidentally siphon out..fun fun fun
