Our Guarantee

We take the worry out of buying Live Copepods, Phytoplankton, Inverts, and Captive Bred Fish online by going above and beyond to take care of our customers. That’s why we guarantee every order we ship will be 100% Alive On Arrival or we will replace it free of charge. Booya. We’ll even cover the shipping on the replacement no matter which service you choose. Double Booya.

About our policy: When your order arrives, be sure and inspect the contents to ensure everything is looking alive and well before you add them to your tank or put them in the fridge. We’ll give you 12 hours after delivery to make sure you are completely satisfied.

“We will take care of you and make it right”

If for any reason you decide something isn’t quite ultra grade, simply snap a photo of the unopened item(s) you would like replaced. Be sure to get the expiration date on the back label in the photo. After that, visit and submit the form. We’ll review the photo and have a replacement out to you faster than a six-line wrasse at feeding time.

Captive Bred Fish: We guarantee every Live Fish we ship to be 100% Alive On Arrival and we also offer a 7-day health guarantee on all Live Captive Bred Fish. In the event that your fish arrives DOA (Dead On Arrival), simply take a photo of the fish in the unopened bag/jar within 2 hours after delivery and visit to submit the form. If the fish is DOA, we will offer you a choice of either a full refund or a free replacement, including the shipping cost. If the fish expires from natural causes (this does not include being killed by tank mates, jumping out of the aquarium, being acclimated to the wrong environment, not being fed the recommended foods) within 7 days after delivery, just provide a picture of the expired fish and we will offer you a free replacement, however, you must pay for shipping, or a refund, less the shipping cost. We can offer this industry leading guarantee on all of our live fish because Captive Bred fish are generally healthier and hardier than their wild-caught counterparts!

Red Ogo Gracilaria Live Macroalgae Gracilaria Parvispora

The Red Ogo Gracilaria parvispora plant is an exceptionally beautiful macroalgae. Between bright red and bergundy in hue and graced with short bushy fronds, it adds a splash of color and texture to any refugium or saltwater aquarium. Red Ogo Gracilaria is a fast growing and hardy macroalgae when kept under proper conditions. It is also great for nutrient export in saltwater aquarium systems. Additionally, it is prized by many herbivorous fish keepers (especially tangs) as a healthy live seaweed food. Pro Tip: Red Ogo Gracilaria can be grown out in the refugium and new growth can be trimmed and fed to herbivorous fish as a tasty treat.

    Love it! It’s growing nicely in the refugium. Golf Ball size is perfect size.

    Love but we got the tennis ball size and its beautiful but huge. My tang has started to nip at it already she loves it. Thanks a bunch.

    In my system, this stuff is far outpacing my Chaetomorpha.
    I got a golf ball sized piece when I was cycling my tank. I set it up in a refugium with a Red + Blue LED on reverse light cycle.
    Phosphates dropped from 0.50 to 0 in the span of 11 days! In the past month I have harvested roughly two softball’s worth of Red Orgo and still have a healthy chunk growing in the refugium.

    My Tangs LOVE it way more than dried seaweed. I occasionally grab a piece from the refugium and put it on a clip. It doesn’t last long!
