That Fish Blog – Aquarium Advice and Information

Many other blogs have discussed (and will continue to discuss, I’m sure) the importance of testing various levels in your water and its effects on the overall health of your aquarium. But, how can you actually test it? For anyone who isn’t able to bring a water sample into That Fish Place or their local fish store for testing or who wants monitor their water quality at home, there are lots of options for what tests to use. While what to actually test for is for another blog, there are lots of options when it comes to how the tests are actually done. Here we’ll look at the pro’s and con’s of the three most common aquarium testing methods: Test Strips, Liquid Test Kits, and Electronic Testing Equipment. Read More »

There are many specific groups of cichlids that develop fanatics and devotees in the hobby. Some species of cichlids just have something special that keeps bringing hobbyists back for more. Certainly one of those groups are the pike cichlids. The pike cichlid genus, Crenicichla, contains more than 100 species ranging in size from dwarf species of around 3 inches long to large predators that can easily exceed 16 inches in total length. These fish are found throughout South America from Colombia to Argentina. Pike cichlids have long, cylindrical bodies with large, wide mouths made for eating large prey. Even the dwarf species boast a healthy appetite for things that you would swear are too large for them to eat! Read More »

Hello, Frank Indiviglio here.  Many of the 2,700 scientists involved in the Global Census of Marine Life are meeting this month (October 7-10, 2010) in London to discuss the information they have gathered over the past 10 years.  In what is surely one of the largest scientific collaborations ever undertaken, researchers studied creatures ranging from microorganisms to whales in habitats stretching from pole to pole and shoreline to ocean abyss. 

Grand Ecosystems and Grand Studies

It is impossible to overstate the importance of the world’s marine habitats and the billions of organisms that make their homes in them – from providing one half the world’s oxygen and much of humanity’s food to influencing climate the world over, their influence cannot be escaped.  Read More »

Nearly a month ago, I was able to represent That Fish Place for MACNA in Orlando, Florida. MACNA (Marine Aquarium Conference of North America), is one of the oldest and largest marine aquarium conferences in North America. Each year you will find new/advanced technology in the hobby, new companies, and of course, livestock. This year was all about LED technology, which seems to be the future of lighting in the hobby.

Amongst the chatter of LEDs was the talk of Papua New Guinea and the SEASMART program. Last year in Atlantic City, SEASMART attended MACNA in the attempt to raise awareness for the need to collect livestock sustainably with an all new approach. Dan Navin, a close friend of mine collected some information on the program while we were there. He made a side trip to Papua New Guinea while vacationing in Australia to check out the operation, a few weeks later. Needless to say he liked what he saw, and is now the SEASMART MAR (Mariculture, Aquaculture, Restoration) Division Manager.

Many freshwater aquarists use or at least have heard of using salt in their freshwater aquariums, but few seem to know why. Most “read about it somewhere”, “heard it from someone”, or “saw it on the shelf so I must need it”. To some, it may be beneficial but to others it can cause far more harm than good.

What exactly is Aquarium Salt?

“Salt” is a very broad chemical term and can refer to an unlimited combination of elements. The salt used in freshwater aquariums is Sodium chloride (NaCl). This is NOT the same thing as what is probably in your kitchen and is NOT the same thing that saltwater aquarists use for their corals and clownfish. The “table salt” used as a condiment is mostly NaCl, true, but most table salt is Iodized Table Salt and contains iodine, de-caking agents, and possibly potassium or other trace elements. The marine salt used in saltwater aquariums is mostly NaCl, also true, but has buffers and other elements like sulfate, magnesium, calcium, potassium and others. All of these extra ingredients can range from unnecessary for to harmful to freshwater aquariums, affecting the biology of freshwater plants and animals directly as well as changing the water chemistry in the tank. For freshwater aquariums, use only salt sold as freshwater Aquarium Salt or pure NaCl like Kosher Salt or Rock Salt. Read More »
