Their appetites are linked to salinity, if their isn't enough salt they stop eating, when their is enough salt their appetites should be ferocious.
1.001 is a little salt you spilled into the aquarium by accident lol
1.005 is low brackish
1.010 is medium brackish
1.015 is high brackish
1.020 is low marine
1.025 is perfect marine
1.030 is too high marine lol
