Fishless Tank Questions

[Beverly]

Am pondering what to do with my now empty 67g and thought I might make it an lps and softie tank with stock from my 37g cube. Cube would possibly be a cap only tank with no fish/shrimp (that are currently residents).

Questions:

- With no fish or shrimp, just snails, would I have to feed the tank?
- If so, how often, how much and what should I feed it?

TIA for your input.
