Paint the inside of QT tank

[hwttdz]

Do you paint the inside of your quarantine tank? I have a fish in quarantine now (being treated with copper, seems to have some sort of external parasites, wish fishy the best) and looking in from the top the reflection is almost mirrorlike. I've heard of people painting the inside of the tank with matte black paint to minimize reflection. Do you? What sort of paint do you use.

Nope, no paint. Unnecessary.
