Peppermint shrimp are great at taking out aptasia.... But, if there isnt any, sometimes they find other things to mess with. Maybe not all of them. But I watched a couple that I had in my system shredding a healthy head of frogspawn one night. Noticed some of my frogspawn was looing less full for a few days, couldnt figure out why for the life of me. Just happened to see it as the lights were ramping down for the night. Granted, at the moment they were messing with it the frogspawn was retracted so far into its skeleton that you could see the skeletal ribs on the edges. It wasnt open at all. But your PS mileage may vary!
IMHO the torch you have looks more upset about flow, light and/or water parameters though.
