Confused and disappointed

When I watched Cory's fish go nuts for this food, I ordered it immediately. I don't know why, but when I pressed the tab on the glass, the only fish to recognize it as food were my balloon mollies. The neon tetras would eat the bits that eventually flew in their direction, but the glow fish, catfish, and guppies wouldn't go near it. Puzzling for sure. It was too much food for the tank and made a mess.

Great Stuff

Fish really like it, sticks to glass, less mess, can't complain, Sera is quickly becoming one of my favorite fish food companies.

Enjoyed by all

Photo attatched of my 55 with guppies bamboo Amano cherry shrimp Otos and sterbai corydoras. My guppies were raised on the small fish fry food from the coop (great food for small mouths) so this was confusing to them at first but when not offered they tear this tab up. I got the largest container as worst comes to worse my fish don’t enjoy it my sister could have it. Sorry sis. 😅 While they’re eating it above it does sprinkle down to the substrate which my Cory and shrimp then go after as seen in the photo. All in all a good supplemental product.

Really good fish food

Effectively every fish i own other than my barbs go insane for this stuff. even my plecos go after it which means it is a decent way for me to see them more than once a month .

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 shipping@aquariumcoop.com 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.
