Who Gives A Fish Forums

I've recently added a gigas clam to my tank and it's taken up a lot of space, so I'm in the process of rearranging my coral. What I've found is that some of my LPS coral seem to coexist peacefully - my open brains, donut, and plate coral all get along fine and don't appear to harm each other.

I was wondering if anyone has experience with how aggressive duncan coral is, particularly when paired with these types of coral, as well as possibly xenia. I'm assuming frogspawn might be too aggressive and wouldn't be a good fit.

I've had my duncan for a bit now, and it's been a real gentle giant - never had an issue with it stinging any of my other corals. Actually, I've found it's quite the opposite - it's really sensitive to being touched by other corals. If my xenia or kenya even brush against it, it just won't open up. Not an aggressive coral in my experience, that's for sure.

Honestly, I'm not familiar with how a clam would interact. That being said, I have witnessed one of my duncans take a sweeper off a torch, and that torch has a pretty harsh sting - it's not a coral I'd want to mess with.

Mine's been pretty chill, never seen it bother any of my other corals, usually it's the one getting bothered instead.

I've had an issue with my Duncan, it stung and killed some Xenia that were trying to move in on its turf. They've since adjusted to a different area, but the affected Xenia has browned out.
