Mr. Nitrite

Flash is my mom's rainbow fish that got sick during high Nitrite levels. If you are wondering what Nitrite is, it is a type of bacteria that is harmful to fish. Anyway, Flash was sick, and even when the Nitrite level was gone, he was still sick. A change from .40 to .00 didn't help him, but after a week or two Flash was fine. I nick-named him Mr. Nitrite, and he sure deserves his nick-name.
