Thought about buying 9 of them and then capturing them when they have cleaned houseWell they're big so they eat a lot. And they eat bubble.
They are slow moving and have tiny little shrimp claws so shouldn't be a threat. Maybe they'll go after coral but I heard if they do it's not to eat but to wear as a hat.
I'll probably have one available in a little bit once they clear my frag out.
