I'm not experienced enough to advise you but I think you will find this problem has been covered many times on this forum.
The search feature is your best friend..... use it.

Is it the fungus? Have you got salt in the system? yep there is the occasional thread about silvers dying...

First things first, with most fish health issues, they are often related to water quality.

So you should start by listing your water test results (ie. ammonia, nitrite, nitrate, ph)
and include temperature of the water.

Then give some information of your system, ie size of tank, volume of growbeds and how often you run your pump, etc.

How long have you got your system?
How long have you got the silvers?
What size are the silvers?

As with most problem solving, the more information you provide upfront, the faster someone can provide you with a possible solution or recommend something to try...

Photos would be good too if you have them..
