I don't know anything about the Sally Lightfoot, but the rest of the inhabitants look shrimp friendly I believe.
How'dja fix your PH
problem? Use the cone shaped screens for the intake? I've had snails and everything climbing on my Maxi-jet 600, 900, & 1200. Got snails and everything climbing on them with no fatalities to date. Only shrimp molts from time to time though.
Might try a few peppermint shrimp too. They stay in the background except when feeding and will keep any aptasia at bay. Lot less expensive than cleaners too.
