It was only a brain fart.
And the little tank must hold only about 4 cups of water. No pump. No filter. Just the frog, some gravel and a rock. And a lid - the very important lid.
She's had that frog for well over a year now. That's a record in my book.
And as I sat there watching the frog swim, I thought "Gee, I wonder how it would do in a larger aquarium..... Just like the one that I have that is now empty..... How much better it would be with a pump and a filter...... We could have several frogs.... A little froggie family....."
NO NO MUST RESIST!
