How to Raise a Piranha
Room to Move
Piranhas can seem cute when they're small and hiding among tank decorations much of the day, but they don't stay small. Depending on the species, adult piranha can be 12 to 16 inches long.
They come from river environments and live best in large tanks -- a 100-gallon tank suits a single adult piranha; add 20 gallons for each additional piranha. Red-bellied piranhas tend to school in the wild, so you can likely keep a few in the same tank, although they might attack each other at some point. If you're keeping a black piranha as a pet, house him alone -- he's just as likely to eat another piranha as the dinner you provide him.
Ringing the Dinner Bell
Piranhas aren't strictly carnivores, although meat is definitely their meal of choice. If you have aquatic plants in your tank, you might see your fish take a few bites here and there. They also eat fish pellets and flakes occasionally, and they can benefit from the vitamin boost these foods provide. But for most of their meals, plan on feeding protein such as krill, mealworms, earthworms or feeder fish. Unless you raise your own under controlled conditions, thaw frozen versions of these foods or buy live ones from reputable fish food suppliers. Avoid grabbing insects and worms from your yard -- they might have ingested chemicals such as pesticides and herbicides, which they can transfer to your piranha.
Juvenile fish need to be fed up to four times per day, while sub-adults usually need food about twice a day. Feed mature adults about once every two days.
Home Sweet Tank
Piranhas can survive in a variety of tank conditions, but they prefer a water temperature of between 78 and 82 degrees Fahrenheit and a sandy substrate. Juveniles are especially fond of aquatic plants. In the wild, they spend much of their time hiding from predators until they reach their adult sizes. However, adults enjoy swimming among the plants as well. They also like large pieces of driftwood that offer secluded places to rest.
Keeping It on the Up and Up
Before buying a piranha for a pet, check with your local and state regulations. Many states ban piranhas because people sometimes release them into the wild; introducing non-native species can wreak havoc on your local environment. Non-native species can compete with indigenous ones for food, sometimes endangering the other species' survival. Also, state governments often don't want to risk local fisherman catching piranhas unexpectedly and potentially becoming injured. Even if you have no intention of releasing a pet piranha, always follow local regulations.
Safety First
Owning a piranha means taking a few precautions to ensure he doesn't decide your hand looks tasty for dinner. Even small, a piranha has razor-sharp teeth that can easily bite through your skin; as an adult, he can bite through bone to remove entire fingers. To prevent injury to yourself, never dip your hand in the water to feed a piranha. Also, don't place a hand with a wound, even a small scratch, in or near the top of the water -- the blood might attract the piranha, who swims powerfully enough to jump out of the water.
Clean the tank with long tools instead of putting your arm inside, and use a net to catch your fish when it's necessary to move him. He can bite through the net, so don't stabilize him with your hand. Instead, hold a second net under the first to catch the fish if he bites a hole in the first net and falls through.

Beluga Whale In Aquarium Teases Kids In An Incredibly Human Way [Video]
While everything looks normal for the first few seconds of the video, the really interesting part starts at the 46 second mark when one of the Beluga whales sticks his forehead to the glass- making the children laugh. A few seconds later, the whale is seen opening its mouth in a scary manner – in an attempt to mock the kids and scare them. It really does look quite scary as the whale sports a terrorizing look on its usually serene face.
The most incredible part comes at the 1:03 second mark where the Beluga Whale turns back and then scares the kids again – similar to what many humans would do. In fact, it is at that moment in the video that you would probably realize how intelligent these marine mammals are. Following this, the whale tilts its head as to curiously study the strange little creatures it sees through the glass. Enjoying the attention it is getting from the kid audience, the Beluga whale continues to do what it had been doing much to the joy of the kids before moving away.
Beluga Whales are related to dolphins and killer whales and like the aforementioned species, are known to be highly intelligent animals. Like dolphins, Beluga whales are also known to be friendly to humans. This has been once again demonstrated by folks from over at Explore.org who have this year installed underwater cameras on the bow of a boat named Zodiac to study visiting Beluga whales – in real time in the Churchill river. Beluga whales are known to swim upstream in the river during this time of the year, says a report by CBC News Canada.
According to Charles Annenberg Weingarten, the founder of Explore.org;
“They’re curious and they’re somewhat uninhibited in a way, and friendly, and so when they hear the boats they have a tendency to swing closer.”
Unfortunately, this also makes them susceptible to hunters. Around 1500 Beluga whales are killed each year in Northern America alone. The species is however not endangered.

Huge Goldfish Invade Lake Tahoe
A group of researchers from the University of Nevada at Reno discovered and documented the oversized fish, including one 18-inches long. Others had apparently spotted the fish in the waters of Lake Tahoe, but Christine Ngai and fellow researchers were the first to document their existence.
Ngai told KCRA.com, "You just see this bright golden orange thing starting to float up, and you’re like, what is that? And then you take a net and you scoop it up, and you’re like, it’s a goldfish."
Experts believe that people dumping the contents of their aquariums into the lake is to blame for the problem. And it is a real problem. Researchers believe the large fish, which aren't native to the lake, could have a significant ecological impact, including creating a food shortage for native trout. Also a worry, according to Dr. Sudeep Chandra of the University of Nevada, is the goldfish's tendency to spur algae growth in a lake known for being crystal clear.
When Ngai and her colleagues examined the fish, they found that some were pregnant, meaning the problem is likely to get worse.
This isn't the first case of abnormally large goldfish showing up in a strange spot. In 2010, a fisherman in France reeled in a goldfish the size of a large dog.

Goldfish - One Of The Most Common Type Of Pets In The World
Many people think that goldfish are pets for someone who doesn't have much time for pet care. The lifespan of your goldfish depend upon how much care you provide goldfish. If cared for properly your goldfish could live for many years!
Goldfish start off small, but grow to be quite large, sometimes even a foot long, if you take good care of them. First time goldfish keepers usually buy a small tank or bowl to house their goldfish, only to discover that they need to keep buying ever-larger replacement tanks. You should buy a large enough tank at the beginning. You should provide a 20 to 30 gallon tank for your fish. Then add at least 10 gallons to that volume for each additional goldfish you might add. They grow large, excrete a lot of waste and need room to swim in order to be happy!
Food: Goldfish like a diet of flakes, pellets, wafers and sticks
Goldfish Facts:
Do goldfish have ears? They have internal ear bones called an otolith that can feel vibrations. Avoid tapping on the glass since it will stress or even kill them.
A goldfish can survive in an outdoor pond where water temperatures dip down below 40*F (5*C). Some ponds might even freeze over during the winter and the goldfish still survive through to the spring.
