The fish in my aquarium began looking really strange to me so I changed their water and scrubbed their tank out really good and then I got the fish out of the water in the sink, only losing ten or so down the hole and placed them back into their fresh new aquarium.
They still looked weird.
So I took them to the vet and he laughed and told me he didn't do fish.
"But don't they look funny to you?"
"No. Look like fish to me."
"Do you think I should take them back home or what?"
"I think that if you'll leave off the pot smoking for a couple of days, they'll be fine."
And he was RIGHT. Cured them right up. The things these vets know is amazing.
