So I mentioned that I recently stumbled in upon Petsmart's cory sale, and used it to populate my 40g tank with 20 some corys. I am loving the huge schooling action I get, and they seem so happy to be in a big group. Now I am considering finishing the aquarium by adding a large group (10?20?) of otos to the tank, so they can also display that, and just skipping the tetras I was thinking of. But my question is, will a large group of otos starve? The tank is a pladarium, has a bunch of surface plants, lots of leaf litter on the bottom, but few to no plants under the surface. I have otos, but I've never had so many I had to worry about them running out of food. Will they learn to eat, and just be happy to be in a large group, or starve if there is not enough algae?
