BTA help

[chefbuddy24]

Hi there, new reefer here. I have two BTA’s that weee the same size when purchased three weeks ago. The bottom one I can’t get to feed or move, not sure what else to do. Any pointers would be great, the nem doesn’t seem to happy

if the nem is unhappy it'll move eventually unless there is another issue that cannot be seen. The mouth looks like its starting to gape aswell, however this could just be the anemone removing waste, if that's the case it'll be fine.
