whats the size of your silver ??
well, my silver has 8" in a 40 gallon tank, till now have no problem with him. tankmates are 1 bp, 2 plecos (blacks with white dots).
and the RTC is't a good idea, they grow a lot and maybe can even eat your aro.
I've seen a gulper 7" to 8" eating an aro of 13" (just take a look at the bottom dwellers)
