Reef Destruction – Molasses Spill Causes Near Total Destruction in Honolulu Harbor

September was a bad month for Honolulu Harbor and all of the fantastic fish, corals and wildlife that called it home. On September 09, 2013 over 233,000 gallons of molasses spilled into the harbor, sinking to the sea floor and suffocating everything in it’s wake. The cracked pipe that allowed the mess to flow into the harbor was repaired within days, but the damage caused by the viscous mess has been rapid and devastating.

You think of molasses and you don’t think of widespread death, but flood a pristine marine environment with sugary syrup and that’s the result. The heavy fluid ends up being lethal in several ways.  The goop clogs gills, suffocating fish quickly. It coats corals and inverts, robbing them of light, oxygen and water flow vital to their ability to thrive. The sugars are also a rich food source for marine bacteria which reproduce in massive numbers, depleting dissolved oxygen as their numbers grow.  The dissolved sugar alters the pH of the water and also creates what’s called an osmotic effect, basically dehydrating marine organisms whose living cells expel water in an attempt to equalize with their external environment. Within hours the death toll began to rise, and to date thousands upon thousands of fish, inverts, corals and even other animals like sea turtles have perished. 

Unlike oil spills that may be wicked off of the surface of the water, the nature of this spill means that cleanup of the molasses itself is not an option. The syrup will dissolve and nature will slowly eat it up and wash it out of the harbor and into the sea. Clean-up in this case means fix the leak, monitor the progress of the damage, and collect the carnage of dead sea creatures that wash up on shores and pile up in shallow areas so that predators like sharks and barracuda aren’t attracted to area. While some creatures may bounce back and return to the harbor pretty quickly, it may be years until the coral reefs, vital to the economy and ecology, in the harbor recover.

What a sad situation. Unfortunately, the only real course of action is to allow nature to clean up another man made mess. On the bright side, nature knows how to take care of herself, and despite the scope of the problem, this particular spill is in many ways still better than oil or some other chemical deluge. Now all anyone can really do is wait and see…

 

 

Product Review – Bubble Magus Curve 7 Protein Skimmer

Bubble Magus 7Marilyn Monroe; Tyra Banks; Kate Upton; and now, Bubble Magus. What do they all have in common? CURVES! I’m talking, of course, about the seductive Curve series of skimmers from Bubble Magus. What makes these vixens of skim different, is a dramatically curvy body that builds on the already popular cone skimmer design. This allows the skimmer to perform even better, as the microbubbles take a turbulent-free ride up its serpentine sides. The SP2000 pump is conveniently placed inside of the body, keeping the Curve 7 protein skimmerfrom taking up too much real estate in your sump. The bottom of the skimmer also features a mysterious red plug, which I later found out was to be used if you decided to upgrade or replace the current pump with a different brand, like Sicce. The plug pulls out and allows for differently configured pumps to fit nicely into the body of the Curve. Then you just plug the hole left by the former pump, making the Curve very, very versatile.

“My Fish is Floating” – Swim Bladder Disease in Goldfish and Others

Most goldfish owners have encountered fish that suddenly become unable to submerge.  Try as they might, they float, often belly-up, at the surface, and seem to be in great distress.  Less often, the hapless victims may be unable to rise to the surface, or may swim in an “off balanced” or head-down position.  Fantails, Orandas and other strains with rounded bodies are the most common victims, but Comets and others are not immune.  The problem is also frequently seen in Bettas, or Fighting Fishes, but may afflict any species.  Swim Bladder Disease almost always involved.  This condition is actually a general term applied to a wide variety of ailments, rather than a specific disease per se.  Today we’ll look at its causes, prevention and treatment.

Fish with Swim Bladder Disease

The Swim Bladder

The swim bladder is a sac-like organ located in the abdomen of most bony fishes, but is absent in the cartilaginous fishes (sharks, rays and their relatives).  The lining of the swim bladder, and the many blood vessels that transverse it, allow gasses to be passed into and out of the organ.  Goldfishes and certain others are also able to exchange gasses through a duct or opening in the bladder that leads to the esophagus.  In this manner, fishes control their buoyancy, or ability to float and move up and down in the water column.

Introducing High Quality New Era Fish Foods at That Fish Place

New EraFor as long as this blogger can remember, when it comes to feeding your fish there have only been a few options available to the concerned aquarist. You can try to find those rare-gem high-nutrition flake foods that won’t quickly pollute your tank if add too many. You can spend top dollar for a hard pellet that your fish have to bite and spit out several times only to let it fall to the gravel to be ignored. You may even have frozen cubes of fish food sitting in the door of your freezer right next to the ice cubes and Creamsicles, much to the abhorrence of your significant other.

Fortunately for us fish geeks, a New Era (pun intended) of fish food has dawned upon us. UK based company, New Era, has produced a game changing array of innovative foods. They uniquely manufacture their foods with a slow, low-temperature, and low-pressure process that maintains the nutritional content of the formula, unlike foods that are quickly baked at high temps have many of their natural vitamins and minerals cooked away. New Era’s processing method also leaves a soft, highly chompable pellet that your fish will be able to eat in the first bite. These pellets are soft enough that you can and roll them into a ball in your finger tips or break pieces off for smaller fish.  But don’t let this texture fool you; they won’t melt and or dissolve away instantly in your fish tank. Between the quality of the ingredients, and unique palatability of the food, your fish get more nutrition with less waste, ultimately leading to a cleaner aquarium. Read More »

Vacation Fish Care – Ensuring Your Aquarium’s Health While You Travel

automatic feederWhen you and your family go out of town on vacation or for the holidays, one important consideration is who takes care of the pets? You can board your dog or cat, or have a friend take care of them while you’re away with a set of pretty basic instructions for feeding and walks. Vacation fish care may take a little more preparation and training to ensure that your tank is cared for properly and any dire issues are addressed.  Generally, depending on the duration of your time away, you’ll want to have a trusted and competent friend come to your home to monitor and feed the tank.  Here are some things to consider in preparing that friend to successfully care for your tanks.

Feeding

Feeding is probably the first thing people think about when you think about leaving your fish for a few days. If you’re going away on a short weekend trip, chances are your tank will be fine without feedings, unless you’re keeping fry or some other “special needs” class of fish. If you’re going to be gone longer that 2 or 3 days, you’ll want to either invest in an automatic feeder or vacation food blocks, or leave detailed instructions with your tank-sitter on what, when, and how much to feed. Generally a few pinches of community food will be enough, but it may be much more complicated with a large reef aquarium or one stocked with various specialized feeders. If you have a complicated feeding regime, or if you’ll be taking an extended vacation, it’s probably a good idea to print a detailed list of instructions on feeding as a reference, and to go through the process at least once with your sitter in person to prevent overfeeding and other mishaps.
