Beautiful moss balls at a great price

My LFS sells these guys for 7.99 a pop. Though I love supporting them when I can, I really wanted to get more than one, and for that price I couldn't justify it. Also I'm really glad I went with aquarium co-op's moss balls. They were nicely shipped and the quality is there folks. Beautiful, velvety plump moss balls and all a nice deep green. Looks great in my nano tank 😁

High Quality

Arrived neatly packaged and very healthy. Great addition to the tank!

Snail eggs on ball

They are beautiful & of them full of snail eggs , I couldn’t recognize earlier. i emailed a picture to aquarium co op.then I get to know.I was little upset as I already put that ball in my aquarium.i removed the ball immediately.
‘our plants have snails. We believe snails are a beneficial addition to a balanced ecosystem in your tank’.
This is the response I got from the company.
If it is a snail I could remove it not a big deal, but thousands of eggs are stuck tight there made it impossible to wash it off.

Love Them

These were much larger than I expected and look really good in my aquariums. I'm very pleased and will probably order more when I set up more tanks.

Great service

Great service, product arrived in great condition.

Live Arrival Guarantee
We guarantee our live products will arrive alive. We ask that you do your part and minimize the amount of time our packages sit out in the elements. It can also be a good idea to avoid ordering live items during extreme temperatures. This would be when night time temps are below 35 and over 80 degrees during the day. Now these temps are not for sure death, it's just what makes it easiest for all of us during shipping.

When temperatures are cold we will use heat packs and extreme cold styrofoam liners. Shipping live goods is difficult as our warehouse could be 70 degrees and your home could be snowing, and all the stops in between. We do our best and will make it right for you and may request to try again at a different time.  During heat waves, it's best to avoid ordering live goods as ice packs etc don't do enough to mitigate it. 

30 Day Return Policy
Our goal is to provide a fair way to satisfy our customers and not lose money while doing it. We make every effort to fully disclose how our products work and what is to be expected. A damaged product during shipping is an automatic replacement from us. When it comes to a difference of opinion such as: "My fish doesn’t like this food." That we don’t refund for. However, if you decide the light you bought is a bit too green for your liking, provided it is in the original box, within 30 days and purchased from us, we will refund it at your cost of shipping.

If you would like to return a product, start the process by emailing us at This allows us to see if there is something we can do before returning the product such as a feature you didn’t know about or send you a return label. We don’t require an RMA number, but do ask you to contact us to initiate the return. Please do not call the retail store as they operate separately from the warehouse and will not be able to issue you a return label etc.
