nocturnal pest anemone

[Alberta-newb]

Tagging along, I've got a couple of these as well and are nocturnal as you have described. Would love to learn more about them. They haven't spread so far (1 year since I set up) and don't seem to be an issue. Not saying they aren't a pest as I also have one mojano that only split into two in the same period....not a pest yet, but they're going out this week anyway just to be safe

I know it sounds weird that its nocturnal, but at night it closes right up and simply looks like zoa almost? but it has more of an hourglass shape, not simply round.

There are a total of three in my tank that I have found. I had a mojano once before, but it actually looked like a mini anemone, but this reminds me more of aptasia or a polyp.

Any more ideas?

The disc is about one cm in diameter, it has a white line going through half of it... and on a seperate on in my tank - the white line goes the whole way.

to me it looks similar to this black sun coral?

It looks alot like the black sun coral....and would explain the nocturnal part.....does it have a skeletal tube or anemone type tube?

no doubt in my mind. majano. You have to remember that majano is not a single species; i believe it is a genus of anemones... not sure. Aside from obvious physical differences, there may be behavioral differences between the species as well. anyways, I've had these nocturnal majanos as well as the diurnal ones.
