Tetra white mouth growth #1
Hi everyone,

I have a problem with a few of my neon tetra. Some of them have a white growth around their mouths and Melafix/Pimafix is not curing it. Does anyone have any suggestions? I've attached a picture to this post. Cheers!

You need something stronger than those. Try Esha 2000 or Waterlife Myxazin.

Thank you! Would these both be compatible with nerite snails?

No, nerite snails don't tolerate copper.

The best option would be to quarantine/hospitalise the affected neon tetra for treatment in a separate tank/container (e.g. a large Really Useful Box or other plastic container if you don't have a spare tank) with heater and spare filter (moving some of the mature media across into it), then return them to the main tank. [It's always handy having a spare heater and filter anyway, in the event of device failure, if you don't already have these - and then they can also be used for this purpose too.]

While you could remove the nerite snails, medicate the main tank and run carbon through the filter following treatment to remove any traces of medication, I think this is risky - there would be no guarantee that the snails wouldn't encounter some traces of copper.

Hope that helps.
