The otocinclus more commonly known as the Oto is arguably one of the most in-demand and popular dwarf, clean-up crew species in the entire aquarium hobby. These fish only reach around 5 cm and are actually quite closely related to armoured catfish such as plecos which makes them a fantastic algae eater species for planted aquariums making them perfect to add into smaller aquariums just as an element of allure or to try out as a breeding experiment.

These guys are brilliant!I have both freshwater and marine and all the fish in my aquariums have come from LiveFish. I live in regional Victoria and the fish arrive alive overnight with heat packs still warm every single time. On top of that their customer service is the best!
Highly recommended.Posted on

Hard working and entertainingI ordered 3 additional Oto's to join my single existing Oto in an established community tank. Well packed, arrived happy, healthy with good colour and very little stress. My existing Oto greeted them with open fins, and everyone got to work cleaning leaves! Great active worker, and highly mobile.
