Question Dwarf cories or ottos?

I guess either way I am going to have to have a group of algae eaters. So now I am trying to decide between dwarf corydoras and Otocinclus spp. Any thoughts?

Oh also another side note, Otos will produce more ammonia than Cory's will :)

I agree corys are cleaner fish. Also be mindful they are shoaling fish and need a group or at least 4, 5-6 is preferable.

I have never seen my corys eating algae, but they do eat decaying plant matter and obviously all the leftover food I eat my fish. Otos WILL eat algae, but only certain types. They also need to be kept in groups of 3 or more. I have both in my tank and I really like them both, but I think the corys are more hardy.

Cories don't eat algae. So it you want algae eaters, go with Ottos. If you want bottom scavengers, go with cories.

Corydoras will eat algae, but not much. Mine love algae wafers but they don't munch on any of the algae elsewhere in the tank. It's not good for their diet though, they need some meat. Mine are on a diet of brine shrimp and shrimp pellets. They eat what my bettas eat.

Otos eat algae, but they are very sensitive. I hear storys of them often not surviving long. They are caught wild.

For my tanks I opted for shrimp to eat the algae build up. Some shrimp are better than others. I have ghost shrimp who will go after fish food over algae. Amano shrimp might be good. Cherry shrimp are really good, but a betta might go after a cherry (depends on the betta). Adult shrimp usually do better with bettas, as the bettas would prefer to eat anything small enough. I use nerites to keep the glass clean, they do an excellent job.

On the topic of shrimp, Ghost shrimp don't actually eat algae, they are just scavengers whereas the Cherry Shrimp and Amano's will eat the algae. But yes, the bigger the shrimp the better when it comes to Bettas :)
