I bought a few of these wee guys for my aquarium a few weeks ago and am really pleased with them. Apart from the fact they all vanished into my filter the first week I bought them, they have been great. They are cute and do a great job of cleaning up algae. They do seem to grow at different speeds though, hence why I now have one I call Shrimpzilla. This isn't Shrimpzilla who I am not sure would fit in the frame anyway and is more of a crayfish but another fairly large one. I think they are too big to insert themselves into the filter now but apparently they can self-propagate in the tank so I may find myself chasing more shrimp with a net sometime in the future!
