cory setup question

A chunk of bogwood would be ideal, since it is part of their natural habitat. The Malaysian Driftwood that is available in many stores works well, as it is often full of tunnels and crevices. It comes in varying sizes, and you could have two smallish pieces.

It is a minor point, but I always prefer decor that is natural for the fish species. So in tanks with corys I use only wood (and plants) because all SA streams have lots of sunken wood branches and logs. Leaf litter is also useful.

Leaving the open space is important as Thoth noted. Always feeding the fish in the same area soon gets them used to it, and is a good way to observe all of them during feeding.
