There is no real need to attack poor english written on this site, i don't understand why some do it.
To the op.......on the other hand if someone does moan about your writing skills it's a good idea to ignore it and don't start calling people "dicks". everyone will help you if you're nice first.
I don't know too much about silvers but if your fish is now on its own its got a good chance, i'm not sure about adding salt for a fish so small so if someone would like to give some input it would be helpful, i would like to know if you can treat small fish the same as you can a larger one, as in salt and temps.
Cheers
