    So far, so good! Arriving in a warm box and looking very healthy, our three little algal eaters are thriving and eating up the overabundance of algae accumulated in our tank. They only arrived two days ago, so hopefully this positive trend will continue!

    A notoriously difficult fish to ship and care for. All 9 of my fish arrived fat and healthy! All have survived. I am very impressed with the care they were given before they were sold and shipped to me. I believe that made all the difference. WELL DONE!

    Second Order was Terrible

    Posted by tara dinicola on 11th Nov 2020

    My first order experience was great, it shipped 3 days after I placed my order, the box clearly stated LIVE FISH. All the 3 arrived live and are still thriving months later.
    However, my second order NOT GREAT. While it did arrive even faster (the day after I placed the order), Nowhere on the packaging did it say LIVE FISH it only said Perishable which made my front desk put it in in the fridge thankfully I picked it up the moment I got the notification so they weren't in there long. When I opened the box 1 was dead, the other 2 where alive but they had this red blotchiness on their underbellies my other Oto's did not have. I put them in a quarantine tank and treated them with a little Primafix thinking it may be a fungal infection but another one took a turn for the worst shortly after and the I'm not hopeful for the last one.
    Overall this is a real hit or miss it seems.

    Ordered the 3 pack and received them the next day. They are the cutest little things! We offered them blanched cucumber and were happy to see that they began eating right away. We had read that it is very important to get them eating as soon as possible. They are doing great so far! Will be ordering more for our other tanks.

    Effectively perfect, there's literally nothing I could complain about. The fish looked very healthy and quite well taken care of. I waited a week to see how they fared before a review, and they're doing great.
    Thank you for the great fish,
