Re Treating The Tank For Fin Rot New Treatment ?

I would carry on with the water changes and watch Moonbeam closely. If his fins start to disintegrate rather than change colour, then start the Myxazin.

All medication added to a tank is absorbed by the fish and it doesn't do them any good. In spring my main tank became infected with a nasty strain of whitespot. After 2 months continual treatment the fish started dropping like flies. I would get up every morning to find more dead fish. I lost over half of them to a combination of whitespot and medication.
This is why I now advocate treating only when absolutely necessary eg fins that are starting to go very tatty and lose bits.

Malt vinegar is OK for testing, it's still acetic acid. With any kind of vinegar you do need to rinse it off well under the tap.
The bubbles don't necessarily mean anything just that the pebbles are slightly porous and the air in them is coming out - displaced by water and of course the tank is warmer than the shop.

Be careful about adding too much iron. Anubias is slow growing so its meed for minerals is small. The floating plants might need it though.

It is a tricky one knowing how sensitive to meds nerites can be. If you leave the remaining snail where it is, it could die. If you put it back in the tank, it could die.
I think I'd risk putting it back but be prepared for its death.


The dead one, are you certain it is dead? They can hide in their shells with the door pulled tightly shut. There are two ways to tell if a nerite is dead. If it is hanging out of its shell it is probably dead, and if it stinks appallingly it is definitely dead. Take a very cautious sniff, the smell of a dead nerite lingers in the nose for hours
