I came to this site to solve green thin string algae growing in my tank, specifically for lettuce sea slugs. While at the site, I also spotted nano red brittle stars, and pistol shrimp for sale too! Everything arrived fine within 2-days by the post office. I put the sea slugs to work by placing them in a patch of algae, they sat there awhile and grazed, then go off to explore the tank some more, and finally return back after resting. They are healthy specimens, larger than I expected. LOL – I had read they need the algae to survive – at the rate they eat the algae so far, the two I have living in my 14 gal nano tank will be around quite some time. I also ordered the nano red brittle star. After two weeks, its still hiding in the rocks. I sometimes have to shine a flash light into the rocks to find it and see it move. As for my pistol shrimp, all I can say is he too is in hiding after 2 weeks. I haven’t discovered more than 1 tunnel so far built. It does not come out yet, but it seems my shrimp goby has found two new spots in the tank to now hang out. Boy, whenever I am ready to move up to another tank size, I will certainly return back to this site to stock it.
