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.
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.
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.
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.
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 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.
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.
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.
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!
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.
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.
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?
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.
You may be aware of the electric light shows that some flame scallops put on. But until now, scientists didn't know how these bivalves created these brilliant visual extravaganzas (no, it's not bioluminescence as many believed) or why they did it.
"Why am I looking at two mugshots on Advanced Aquarist?" you might ask. These two Rhodes Scholars stole a FedEx package from their neighbors porch. When they found out they had stolen live fishes, they did what any sensible person would do: flush the fishes down the toilet.
