Animal House

Now, apparently, even your mollies and tetras aren't safe from the long tentacles of the melamine-contamination scandal that has rocked the pet-food industry.

Sergeant's Pet Care Products announced a voluntarily recall of some lots of Atlantis Goldfish Flake Food and Atlantis Tropical Fish Flake Food because they were found to contain melamine.

The company said the effect of melamine on ornamental fish is unknown, though it suggests that overfeeding likely poses a greater threat than the trace amounts of melamine in the food.

Grouper fish have the option of changing their sex if there aren't enough available mates of the opposite sex. We humans have no such hermaphroditic options.

Instead, there's "Sex and the Sea," a singles social mixer this Saturday, Feb. 11, from 7 p.m. to 9:30 p.m. at the New York Aquarium. The Brooklyn aquarium will have its education staffers on hand to discuss such pheromone-pumping subjects as how octopuses change color in order to woo the one they love. But the hooking up is up to you.

Tickets are $30 for members; $35 for non-members, which includes beer and wine, hors d’oeuvres and on-site parking. You must be 21; call 718-265-3448 to make a reservation.
