I like to keep my tropical marines at about that temperature, so its not to hot. I've had our tanks with clowns go up to 35oC with no problems. As long as it is a steady rise (or fall) the fish don't seem to mind so much. Its the sudden changes that get them. Yes you can put ice in the filter but you may need a lot. I use a 12l block of ice in my 300l freshwater tank wehn it gets to 32oC. this will only take it back to 30oC. the other option is use your air con in the office to help you.

Yes, scientific research has shown in many experiments, that the fish stock inside a closed area recovers (only where these were fished before). Fish become more numerous and bigger. It benefits particularly the large predators. Most studies report an increase of about 2-3 times to what is found outside. However, this affects only the exploited species. The thousands of other species remain unaffected, except that they may be more likely to be eaten by the larger predators.

In 2004, scientists completed a study on the permanent de-facto marine reserve around the Cape Canaveral rocket launch site. They tagged fish inside and outside the reserve and followed their movements. To everyone's surprise, fish inside stayed inside but those outside migrated into the reserve, never to leave. Inside the reserve, the tagged fish were lost, presumably due to predation. The scientists concluded that the marine reserve acted as a sink (like a bottomless pit) to fish.

Fish cannot read maps. They do not know where a safe area begins or ends. The only clue they have is that it is safe where a lot of fish are found (humans do so too). Helping safety in numbers, is one reason why feeding the fish inside a protected area is not a bad idea. There exists a vast difference between migratory and resident species. Migratory species move in and out frequently. Resident species invariably maintain a territory, which they defend against competitors.

It is thought that new recruits drop out of the plankton without preference for where (randomly). Assuming this is true, a marine reserve will receive as many newcomers as outside, per area. But inside the reserve there are more and larger predators (which has been demonstrated), thus their survival chance is less than outside. Marine reserves do not produce more recruits.

Like an oasis in the desert, all forms of coral life are quickly attracted to Biorock reefs. Many forms of reef life have been observed to be attracted to the structures, and none repelled. However it is the organisms with limestone skeletons, such as corals, clams, oysters, barnacles, tube worms and sand-producing algae that are especially benefited, allowing them to outgrow weedy algae that often smothers and kills corals in polluted waters.

This is enough to kill almost all coral reefs now existing, as they are right at their upper limit. Ocean circulation changes will have dire impacts on marine fisheries, which are only starting to be understood.

The maintenance, water quality and equipment are the same for both except for the addition of a heater and Thermometer for the tropical varieties of fish. So if you looking for an aquarium of 20 litres upward, do not be put off by thinking that tropicals are hard to care for. There are some very hardy tropical varieties and some very delicate coldwater ones as well. Here are our most frequently asked questions and answers to help you with your small animal ownership.

You must mean captive bred. Yes, I'm all for captive raised species. In fact several companies are doing just that. Unless the hobbyist is very wealthy, deaths of fragile creatures put a damper on keeping a reef tank for most people, who wants to keep removing dead creatures from the tank? Not very rewarding.What does make the hobby interesting is... exchanging information amongst those who are experienced thereby minimizing costly mistakes.

Fisheries and Oceans Canada has a wealth of information on the various fish and other marine species found throughout Canadian waters. General information can be obtained from the publications section of the Fisheries and Oceans Canada website. Specific information pertaining to fish, invertebrate and marine mammal stocks, environmental overviews and other research documents in this topic area may be obtained through the Canadian Stock Assessment Secretariat.

Yes, but only the general Marine Science units. The specialist units, MARS2007 and NTMP3001-6, are only available to the BSc(Marine).

The zebrafish is a small, hardy fish, about 1" to 1½" long that many people have in their small aquariums at home. The standard "wildtype" variety is somewhat clear-colored with black stripes that run lengthwise down its body. For many years they have been bred by fish hobbyists for home aquariums.

Currently we do not permit people to create or add custom fish for Marine Aquarium. There are many reasons, but the most important is that while we trust an artisan would be motivated, and even capable of creating a truly wonderful masterpiece, there are others that might not, and a version were to get out that was less than the highest quality, it might reflect poorly on us. If you are interesting in creating fish or wildlife for our company, we are always seeking talented artist.

I currently have black skirt tetras and head&TAIL light tetras ,2 african dwarf frogs,1 apple snail ,3 cories and a pleco..I have heard that i could actually add a male betta to this mix if i wanted..I didnt think they were community type fish but if they are would love to get one.. I would not recommend a betta for this community tank. The tetras and the frogs are a threat to the betta's welfare <>>>< I have a 10 gallon tank.

Yes, soft water is satisfactory for most tropical fish. According to several authorities, both fully soft water and municipally softened water would have no undesirable or toxic effect for use in an aquarium. When making the change from hard to soft water, it is necessary to make the substitution on a gradual stepwise basis of new water for old. This follows the basic pattern in regard to any change in the environment for tropical fish.

Tropical Fish can raise the temperature of your pool water by up to 15%. It is completely safe, non toxic and should last up to 30 days.

Well growing plants in an aquarium is more then just having the proper amount of light. Many plants both land and water require certain conditions to thrive. In an aquarium it is necessary to do the proper research on the fish you intend to keep and match the plants to the fish. An example would be setting up a tropical fish tank with fish from the Amazon basin. These would include many Cichlids like Angel fish, Discus, Jack Dempsey, Convicts, Oscars and others.

Hard to say, it's just this tradition. There's this band I'm in (The Electric Fish), it's a reference to one of the first X programs I wrote (xfish), there are 15 fish-objects (stuffed, wooden, etc) in the room where I'm typing this, etc. And I don't even own any real fish.

There is now a new technique. Several dots will appear, once the text "Oh! A Bite!" appears, press A. Continue until the hooked Pokemon attacks.

For decades salmon hatcheries have been producing fish which contribute to ocean and river salmon populations. California has nine hatcheries that collect eggs from returning adult salmon. The eggs are fertilized, incubated, and the juvenile fish released to the wild. The only marine hatchery now in production is in northern San Diego County. It is producing annually about 100,000 juvenile white seabass at this time, and will eventually produce about 400,000 per year.

Marine Aquarium also includes a starfish that crawls along the bottom of the tank and on the "glass" of your monitor!

A real saltwater aquarium of this size could not support more fish, and it also gets visually crowded. The second reason is the graphics overhead for more fish slows the system down too much. We know that many people have very powerful graphics cards, which are producing 100 frames per second, but most do not, and we want the Aquarium to be a satisfying experience for the largest possible audience.

The methods vary, reflecting the diverse aquatic habitats that make up Canada's coastline and freshwater environments as well as the diversity of species listed under "What species are grown commercially in Canada." Freshwater fish are raised using enclosed freshwater ponds; holding tank systems fed by well-water, stream flow-through, or water re-circulation systems. Both freshwater and marine fish can also be farmed using net-cages suspended in lakes, estuaries or in open-water coastal sites.
