Elephant slug actually NOT reef safe?

[Petrichor]

Just wondering if anyone else with an elephant slug has had issues with them not being reef safe. My initial research led me to believe they were reef-safe, however I have noticed something eating the edges of my leptos, select soft corals (RIP kenya tree), and sponges over the past couple of weeks.

The only other option it could be would be a brittle star or halloween hermit crab which were added at the same time, and the halloween hermit can't reach most of the corals (except the kenya tree) as they are on a rack halfway up the glass.

Nothing else in the tank except various other corals, clean-up crew snails, and a porcelin crab. No aggressive corals around the affected ones either.

Never heard they could be not reef safe.
I have had them in several tanks over the years and haven't seen anything that would indicate they were eating any corals from softies, to lps to encrusting sps.

I have heard of issues on rare occasion with certain species, but to have issues with stony corals, softies, and sponges would be beyond the scope of any issues I have heard of; are you sure the damage is from something eating them and not something else?

I've heard that some Elephant Slugs (Scutus spp.) may go after SPS on occasion, but I don't think I've heard anything negative about Black Stomatellas specifically.

Edit: For clarification, Elephant Slugs often look basically like giant Stomatella snails, and they're frequently black in color too.
