Fish Facts

Fish do yawn! An occasional yawn is normal! If all the fish in an aquarium are yawning every few minutes or so, call us. This may indicate a dissolved oxygen or temperature problem.

Blue Tangs (saltwater) when stressed or scared, lie on the bottom of the aquarium on their sides until they sense that all danger has passed. If your Blue Tang is lying on the bottom of the tank, and its gills are still moving, it isn’t dead. It’s playing dead!

Both saltwater and brackish water Puffers lay on the bottom of the tank periodically, especially after eating.

If the aquarium water turns cloudy almost overnight, always check to see if all the filters are running before calling us. A white cloudy, swirling condition (looks like someone poured a little milk in the tank) may indicate ammonia. If all the filters are running, count your fish, and check their condition.

Fish have wonderful cells in their skin called melanophores. These enable almost all fish to change their coloration and markings at will. Some species can change their coloration and marking pattern in less than one-tenth of a second! Fish may change their color when they’re sleeping, stressed, attracting a mate, defending a territory, or eating. Some fish have several coloration schemes for different functions, such as camouflage. If a fish in your aquarium has changed its color or markings, there’s nothing to be worried about, unless the fish maintains the different coloration for more than several hours. This may indicate major stress, and you should take action immediately. If ALL the fish in the aquarium have changed color, this usually indicates an urgent emergency situation!
