High Maintenance Fish

My son came home with beetles, I said, "No, No, NO."

He came home with a worm and I said, "No, NO, NO."
Next he came with fish, and I said, "YES, YEs, YES." 

Tell I found out they were high maintenance fish and then I tried to say, "No, No, No!

These are black light sensitive fish. We have lost two of them, but the pink one seems to be hanging in there. What fun.
