The cories are awesome and I love that they swim around the middle level of the tank. They don't stay on the bottom like all the other cories. They are small! Males only about 3/4" full grown and females slightly over 1" full grown and of course have rounder abdomens. They do not eat any fish eggs or fry, even their own and it's said that they are superior to any other snail, cory, or shrimp for cleaning the tank and keeping the bacteria level down. I acquired this group from Eric Bodrick who is one of the top rare fish cory breeders in the US and am working on getting some more breeders from Frank Falcone (aka coryologist) the other famous US rare cory breeder. With some luck, I'll have babies to sell in the coming year.
