I have two clownfish (false). I got them a week ago today LFS said brine shrimp but wait until Friday. I was to give the half a cube. They did nothing but eat it an spit it out. They my be eating 1 percent of a half cube. So I got mysisa shrimp same thing. This is day 7 what to do. Today I added garlic guard with same results. Parameters are 8.3 ph and 0 on everything else. The fish act fine look clean and healthy. What is up are they eating it after I leave or what. The amount I have seen them eat they should be die I think. I am worried what do I do. Maybe I am paranoid
