Have you ever had someone look at your tank and askÂ why the live rock doesn’t move? Well now with Eshopp’s new MVI 3146 you can have that moving live rock look you’ve always wanted. The MVI 3146 might run on electricity but if you ask us it, runs on cool. The ultra-realistic reef comes with preatached frag replicas, but you can take those off and add your own frags. Imagine, you could be the first reefer on the block to turn your fruit stand reef into a full blown poseur coral display case. Larger models with optional laser or led light show will be announced soon.
