Looks like a milipede to me. Not an insect to be worried about, they enjoy eating decaying matter (soil). I have some in a couple of my houseplants and have seen no ill effects. I'm guessing they were present at purchase because I've never put my plants outside.

You can pick them out of the soil as you see them, but I wouldn't worry about "getting rid" of them. I've read their poop is better for plants than earthworms (now how true that is, I don't know). But, they're not a pest that you need to be bent on getting rid of, they won't eat your plant and they're more of a beneifical insect.

Yes, it sure looks like a centipede!

Or that, lol. Centipedes are also not of concern. They are more predatory insects than pests.

Millipedes have 2 pairs of legs per segment. Centipedes have 1 pair. But since the OP is in the Maldives the creature might be something completely different and might or might not be a problem to the gerbera.

My initial guess was a millipede(once I actually saw the thing),and now after zooming in on it,I'm still pretty convinced. There are what appear to be two legs per segment anyway.
