Starfish-eating shrimp questions

[treylane]

I've had a recent explosion in asterina stars in my 200g tank.

While I don't really mind the starfish, I've been curious about getting one of the starfish-eating shrimp available to the hobby -- harlequins, bongos, or bumblebee shrimps.

The thing is, I've also got two large (one is 6" across and the other is 12" across) spiny brittle stars. They're much faster than an asterina but nowhere near as agile as a serpent star.

Does anyone have experience with these shrimp, to be able to say how aggressive they are with attacking different varieties of starfish? Do they have preferred size/species of prey? Could they take down a larger star?

I had a harlequin shrimp a few years ago. No stars are safe

I had to train my harlequins, put them in a guppy breeder and just feed them the small starfish. They never went after brittle stars from what I can tell, but yes they can take larger stars once they flip them on there back

It is impressive seeing them flip a large chocolate chip starfish with ease.
