The combination has been known to work. I would add a third large tankmate. Hmmm some sort of cat (not too huge though) or another silver.
SInce the price is interesting then i think it is worth the risk. If it works - good. If not, then you still have one. Odds are in your favor since silver is quite a lot larger than jar. No, silver will not eat your jar (very unlikely)
