Hey guys i got 2 new anthias to add to the 2 already in tank. Iv had them for 5 days now and they still not eating . One always hides in rock crevices barly swims ever and wont eat. the other swims in the open and and is active but wont take food. Gave it a few days trying frozen eggs frozen brine and different pellets. Still no interest in food. Any idea what i should do. Thinking of going mississauga big als and get some live brine shrimp.
