Otocinclus hardly needs an introduction. Notoriously difficult to acclimitize but are actually very hardy when established. Does best in groups, and plants definitely bring out the best in this fish.

Really Under Appreciated...

They are relegated to janitors in most community aquariums, but truly come into there own in well planted tanks. Sure they do nice work, but I enjoy nice robust Otto's. ;)

best otto's

The best otto's are a bunch of otto's :D ! Once the numbers I kept exceeded 6 per tank they really came into their own. I've yet to find a negative point to having these fish.

There's a manager at a local pet store here in town who keeps over 200 of these little guys in a 500g low-tech planted aquarium. I have yet to see it my self, but wonder what the behaviors look like in a group that large.

I have 8 of these guys in my tank (50 Gallons), they are the best algae eater I've found (much much better then SAE's), they are great for getting rid of brown algae apparently it's their favorite type to eat. They also do a great job on the regular old green algae.

I have to agree that these fish don't get their full due, they are an interesting fish to watch when in groups, they seem quite social.
