Summer to Winter in Fresno

By Aletha Lang

An aquarium heater should be considered a critical piece of equipment for your aquarium, just like a filter that is essential to the lives of your tank inhabitants.

As we who live in Fresno and in the San Joaquin Valley well know, our seasonal temperatures vary from summers at 105 degrees Fahrenheit or more to winter temperatures as low as 32 degrees. So winter is a great time to check your heater to be sure it is operating as you expect it to. Heaters do go bad and rather than assuming yours is working because the light’s on or because its dial is set at the right temperature, be sure to verify that it’s working properly by checking the actual temperature of your aquarium water with a trusted thermometer. Tropical fish (both freshwater and saltwater) require water temperatures to remain very stable in order to survive. A narrow range from 77 to 82 degrees is ideal for most.

Perhaps you’re already aware of the stresses extreme temperature swings can cause your fish: parasitic outbreaks, lethargy, uneaten fish food sitting on the bottom of the tank. The latter is not a direct, but rather an indirect result of the fish not feeding normally in cold water, and we all know that rotting food leads to degrading water quality.

So before you lose any fish, check your heater today. And please contact us if you need a replacement!

Sea stars

By Aletha Lang

People often ask us about the California tide pool touch tank on display during Aquarius Aquarium Institute’s educational outreach programs.

These sea stars and other animals cannot survive in the typical home aquarium and are actually illegal to possess without proper permits.

For more information about the Institute’s educational programs and to request that the animals visit your child’s school or birthday party, please e-mail Aletha Lang or call 559-490-3474.

Pulsing Xenia

Here is a video focused on a living coral growing in one of our client’s brand new coral reef aquariums. Watch how its polyps, like little hands, grab for plankton in the water as hermit crabs busily clean the beautiful purple coralline algae-encrusted Fiji live rock around it.

A Personal Favorite

Adult blueface angel – we had this one for 15 years!

By Aletha Lang

A personal favorite of ours for the saltwater fish-only aquarium is the beautiful blueface angel, Pomacanthus xanthometopon.

Although some individuals may be considered reef safe, blueface angels will most likely eat the polyps of corals and nip at clams and zooanthids. They do best as the showcase fish and do well on commercially prepared food. Those frozen foods that contain sponges and algae are best for their health.

The juvenile blueface looks much different than the adult – both spectacular!
