John Duncan –
Received the Giant Otocinclus Catfish in great condition. It’s larger than expected and very active in the tank. The algae-eating behavior is impressive and has reduced the green growth in my planted tank. Very happy with the purchase.

The fish arrived quickly via UPS Next Day Air. It’s calm and doesn’t stress other fish. I noticed it’s very efficient at eating algae, especially on the glass and leaves. A great addition to my community tank.

This is one of the best fish I’ve added to my aquarium. It’s peaceful, grows steadily, and keeps the tank clean. The description matched the actual fish. I recommend it to anyone looking for a low-maintenance algae eater.
