How Diet, Lighting and Other Factors Can Influence The Appearance of Aquarium Fish

Red TerrorDedicated aquarists pour their hearts and souls into creating thier own versions of breathtaking aquatic displays. Countless hours are dedicated to precise placement of wood, rock and other ornaments, painstaking pruning of live plants, and,  of course, to testing and maintaining the water quality to provide the healthiest environment possible for the stars of the show: the fish! The ultimate goal is to have brilliant, beautiful, healthy fish to observe, and just about every other aspect of the tank contributes to the appearance of the livestock you keep. While the conditions that favor each species vary, you can provide the necessary factors to tweek the colors they show and make your fish look their best.

Understanding Fish Coloration

The inner layer of each fish’s skin contains color cells called chromatophores. Some chromatophores produce melanin, providing brown or black pigmentation. Some are capable of storing carotenoids which provide brilliant red, orange, and yellow pigments that come largely from foods the animals eat. Then there are iridophores, that contain crystalline deposits that reflect and bend light and giving the illusion of silvery, white, or metallic blue and green pigmentation. Read More »

Winter is Coming – Cold Weather Pond Prep

Pond in winterSay what you will about the changing of seasons, getting to watch the leaves turn from green to shades of red and yellow, and partaking in what are arguably the best holidays of the year (Halloween, Thanksgiving, and that one where we all go shopping), but going into winter is a pain in the pond! Well, this blogger is here to help you overcome your winter-time woes with some helpful reminders of how to get your outdoor pond ready for the winter.

Now, obviously we don’t all live in the same climate; so this blog will likely only be helpful for folks who actually get to experience a winter and all the glorious tribulations it has to offer: freezing weather, snow showers, etc. Those of you lucky enough to only need a light jacket through winter months can move right along with your “lows in the 60’s” weather! If, on the other hand, you actually own a snow shovel, then let’s work on getting that pond ready for the winter with 4 easy-to-follow steps:

Ice is bad, m’kay?

One of the worst things you can let your pond do is completely freeze over when the temperatures drop. If there is no opening in the ice, then there is no gas exchange going on. Your fish might be hibernating, but they still need oxygen to breathe and your pond still needs to release carbon dioxide. Does the whole pond need to be ice free? Of course not! A little hole in the ice would be satisfactory. This can be accomplished two ways: by using an air pump or a de-icer.

Air pumps pump air into the pond, creating bubbles to disrupt the surface of the water and preventing ice from forming. Air pumps are also a nice investment because they are useful in the summer for extra oxygenation when the temperatures rise. Read More »

Keeping Brackish Water Fish – the Silver Mono or Malayan Angelfish

Large, flashy, uniquely-shaped and active, Silver Monos, Monodactylus argenteus, always draw attention when seen for the first time.  But there are many misconceptions concerning their proper care, and new owners often become frustrated with them and move on to other interests.  However, when their unique needs are met, Monos are quite hardy and make for spectacular exhibits.  A group I cared for at the Bronx Zoo, housed with Mudskippers, Fiddler Crabs and Banded Archerfish, proved so interesting that they rivaled neighboring Leaf Insects, Hornbills and Tapirs for visitors’ attentions.

Description

The Mono’s silvery coloration shimmers under light, and is nicely offset by yellow or black fin tips and the jet-black stripe that runs along the edges of the dorsal and anal fins.  The body is flattened and disc-shaped, and the sturdy dorsal and anal fins are much-elongated.  Silver Monos are powerful swimmers, well-able to buck the strong currents common to the tidal rivers and coastal mangroves that they frequent.  If given enough space and a proper diet, they can reach 9- 10 inches in length, but most in the pet trade top out at half that.

Actinic Light vs. Blacklight – Highlighting Fluorescent Livestock and Decor

Glo tetrasWith the growing popularity and availability of fish like GloFish and GloTetras and decorations like our own Pure Aquatic Glow Elements line, “glow-in-the-dark” and fluorescent aquariums are becoming more and more common. Most of these animals and decorations are brightly colored in any light but under special lighting, the colors will really glow. There are two main kinds of light that are used in these aquariums: “blacklights” and actinic lights. Knowing the difference between these two can play an important role in making your tank really stand out, as well as in keeping it healthy. For this blog, we will be focusing in general terms only for community aquariums. Aquarium with invertebrates and corals will have different needs since their light requirements are much more specific and extensive.

First, the science…

The colors we see around us come from the light’s wavelength, measured in Terahertz (THz) or nanometers (nm). Most people can see light ranging from about 700nm (reds) to about 400nm (purples). Blacklights and actinic lights both produce light from the bottom of the visible light spectrum (the BIV in ROY G BIV). Most actinic lighting for aquariums has a wavelength of about 420-460nm. The higher end of this range (460nm) produces a more blue color light, while the color shifts to purple approaching the lower end (420nm). This type of lighting is still well within what we are capable of seeing. “Blacklights” emit a light below what we as humans are able to see known as ultraviolet or UV light. Yes, this is the same UV light that we wear sunscreen to protect ourselves against! UV lighting is separated into three major ranges. Blacklight bulbs are UV-A bulbs (315-400nm), the spectrum which causes our skin to tan. For comparison, the UV Sterilizers popular in aquariums for eliminating algae, diseases and parasites are UV-C bulbs (200-280 nm), a destructive spectrum that is mostly filtered out by Earth’s atmosphere and the UV-B range in between is the more damaging rays from the sun that causes sunburn and other harmful conditions.
