Fish medicine expiry date, does it have an expiry date?

Question

I had this fish medicine to cure the white spot and itch but the bottle doesn't say any expiry date on it. I had it since 2004 or 2005, do you think I can still use it or is it expired already? cause in the bottle it doesnt show any expiry date and Im afraid it will kill my fish if used.

Answer 1

This medicine is a diluted solution of methalene blue and or malakite green and very weak solution. It does not expire and you can still use the solution as indicated will not kill the fish but too much will kill the fish.

Get well Fish

Answer 2

Most fish medicine does have an expiration date, but ich medicine is one of the few that doesn't usually. If the medicine is dark blue it works with a chemical called methylene blue and that does expire so you would be safe to use it.

Best of luck!

Answer 3

The box or bottle will usually have an expiration date on it. personally I wouldn't use solution that old on my fish. For the sake of a few pounds its worth getting a new bottle;
