You can own a piece of fish conservation history

Up for auction is a true piece of American (and Boston) history. Written only two months after the United States signed the Treaty of Paris in 1783, this letter may be one of the earliest US governmental conservation documents in existence. Fish conservation no less. And signed by *THE* signature of all signatures, John Hancock!

Reefkeeping is NOT under attack

At least not by NMFS or NOAA. I really wish reef aquarists and experts alike would stop spouting this "we're under assault" red herring. It's serves only to undermine our own hobby and the animals we all love.

The Fluorescent Maldives

The Fluorescent Maldives

An "ordinary" Acropora (valida or nana?) transforms itself into anything but ordinary!

With the advent of technology, fluorescent night diving is becoming a popular form of underwater photography/videography. Biofluorescence has captured the interests of many reef divers and for good reason: sealife (particularly corals) are at their most amazing when they're transforming blue and UV light into unbelievable glowing colors.

Sisters act together - Cichlid sisters swim together in order to reach the goal

Sisters act together - Cichlid sisters swim together in order to reach the goal

Many fish travel in shoals as a form of protection. But the exact shoaling patterns – who groups with whom – differ from species to species. A team of researchers from the Konrad Lorenz Institute of Ethology at the Vetmeduni Vienna studied cichlid fishes in Lake Tanganyika in central Africa. On their dives, the researchers observed that female fish dispersed longer distances from their natal grounds than males. To minimize risks and to secure the spread of their genetic information, females often swim together in a shoal with female siblings. Males, on the other hand, prefer shoaling with non-siblings. The results were recently published in the journal Oecologia.

A pair of Torquigener albomaculosus in their love nest.

In 2013, we blogged about a really cool Japanese pufferfish that creates incredible love nests on the sandbed which can be best described as geometric art. The Michelangelo of the sea now has a been officially described as a new species.

This is how giants do

Goliath groupers are massive fish that can grow nearly 2.5 meters in length (8 feet) and weigh almost half a ton (450kg). Last summer, scientists documented for the first time how these rare giants spawn.

People really suck sometimes

People really suck sometimes

This is not what anyone expects to see on an aquarium.

A LFS in Lubbock, Texas was burglarized on January 17, 2015. The thieves not only made out with the contents of the cash register, but they decided to shoot up ten stocked aquariums for no reason.

Apistogramma kullanderi, a new showstopper

Apistogramma sp. are amongst the most spectacular cichlids - nay, fish in the world. A new species was added to this genus last month. Apistogramma kullanderi continues the tradition of excellence for this dwarf cichlid genus.

Chelidoperca santosi, a new and spectacular reef basslet

Here is a holotype of Chelidoperca santosi gathered from a Philippine fish market

The story of Chelidoperca santosi's discovery is as intriguing as the species itself. A bright red and orange Serranid (basslet) was found in the mouth of a larger grouper at a Philippine fish market.

Nothobranchius flagrans, a gorgeous new killifish

Lots of amazing new fish species have been described in recent weeks, and we'll spend the better part of this week telling you about them. This is Nothobranchius flagrans, a new killifish from the Republic of Congo.

The secret lives of baby reef fish

We know it's Friday. Just one last educational material for you to soak up before the weekend. We promise it's fun and worthwhile, as most things TED are. Baby reef fish fight an uphill battle to survive into adulthood, but they aren't hapless drifters. The lil' guys are rather amazing, actually!

Laying the groundwork for the Frost Museum of Science's Aquarium

The Frost Museum of Science at Miami, FL is under construction. It took 25 hours, a lot of machinery, and a bunch of people to lay the concrete foundation for the 600,000 gallon aquarium. Here's a fun time-lapse of the impressive process.

Read more about the new museum and aquarium, which is scheduled to open sometime in 2016.

Baby corals go where the zooxanthellae roam

Scientists investigating the settlement of larval Acropora millepora uncovered two neat and unexpected discoveries: 1) Acropora in cooler-than-normal (not warmer) waters made poor choices by not settling on coralline algae and 2) baby corals can actually sense and seek out where the zooxanthellae are.

A washing machine aquarium; don't press spin cycle

A washing machine aquarium; don't press spin cycle

The finished washer aquarium (right) snickers at all the boring run-of-the-mill washer/dryers on the showroom floor.

We've written about aquariums built out of old TVs, computers, and even pianos, so why not one built from a front-load washer? Now how about a matching dryer aquarium?

A Cichlid's Training Day

Sit fish sit. Good fish. Maybe we can't make our fish sit, but there are many tricks we can teach the fish we keep. Fish are much more capable than people have historically given them credit for.

Last summer, we published an article about training goldfish to perform tricks using the R2 Fish School.  By using operant conditioning via positive reinforcement, goldfish are taught to perform numerous feats like swimming through hoops.  This type of conditioning is the same concept used to train a dog to sit.

Cichlid owners know their fish are no dummies either; some would even say their cichlids are devilishly smart.  Thus, it's not surprising to see cichlid performing the same tricks using the R2 Fish School training program.  This unedited training session video was shared on reddit:

Now if only we could teach our fish not to do bad things like rearrange aquascapes, bully other fish, or eat expensive tankmates like your favorite coral.  Maybe we can.

Researchers are constantly discovering that fish are smart animals capable of memorization, recognition, strategic planning, and even tool use.  Scientific studies have also shown that stimulated fish are healthier then those living in sterile conditions.  By giving your fish something to interact with - whether it be a stimulating surroundings, "playmates," or interactions with their owners - you can make your fish smarter, happier, and healthier.  We classically think of aquarium fish as "respectfully hands-off" companions, but maybe that needn't always be the case.

Right, Comet?
