Silver dollars and plants?

[Plec123]

I've been looking into silver dollars... But I have a planted tank. It's 36"x12"x20".
After doing research on other sites, I have found reports of them leaving java fern and anubias alone, as well as crypts and Crinum (onion plants).

Can anyone back up this info? I used the search bar on AC and got mixed results.

The only plants I have are java fern, anubias, crypts, and I may be bringing an onion plant home from my school's tank.

ALSO- would 3 be a good number of SDs for my tank?
Thanks in advance for any help you guys can offer!

I have heard 5 sliver dollars is the magic number....i bought three. My Jardini killed one but the other two are now 5 inches and absolutely nuts. They are supposed to be vegetarians but will eat anything and everything I put in the tank, mealy bugs, trout worms, Hakari sticks, prawn, algae tabs, flake, krill, each others fins(just a little) ....except peas. Be careful with plants!!! Mine would eat them. LOL

Yes they will eat those plants no promblem. 3 is fine in there.

Thant tank will be too small for full grown SD, and they will eat any kind of plants very quickly. A school of full grown SD needs a 6' tank IMO.
