Zoe Mitchell –
I’ve had my Otocinclus for three months now and the algae in my 10-gallon tank has dropped significantly. They’re quiet and don’t stress other fish. Easy to care for and very effective at cleaning the glass and plant surfaces.
Carol Sutherland –
The fish arrived quickly and looked healthy. They’ve been eating algae regularly and have not caused any issues with my community tank. I’m happy with the purchase and would recommend them to others.

My tank used to have a lot of green film on the sides. After adding the Otocinclus, the algae has reduced noticeably. They’re small but very active and seem to enjoy their food.
