__HIDDENCAT__
 * The Corydoras group of fish frequently gulps air. This is normal and is not a cause for concern. If too little room is available between the water surface and the hood (<2") the fish may hit the hood. They hold the air in their stomach and the thin lining dissipates the oxygen.
 * This fish likes the company of its own kind. It is recommended to keep at least 2, or better yet, several of the same species. The more you have, the more secure they are and the more you will see them.
 * They are known to 'blink' their eyes to the amazement of onlookers. The Cory has the ability to tilt its eye down to examine the nearby substrate.
