The Evidence is in: Fish are Intelligent!

By on

Despite having a reputation for being mindless instinct driven vertebrates, fish are actually highly intelligent. So please, no more 30-second memory myths. A slew of recent research has shown a variety of complex behaviors and social systems (which I recently wrote about). While other recent work has focused on the cognitive abilities of specific individuals, as well as their ability to learn from others

Goliath Grouper:1, Black Tip Reef Shark:0

By on

The common name for Epinephelus itajara is goliath grouper for a reason. These things are absolute beasts, growing to over 10ft (3m) long and weighing 800lbs (360kg). They can make meals of almost everything in the Caribbean, including a 4 ft black tip shark on a fisherman's line. Respect the grouper!

Goldfish playing Streetfighter II is apparently a huge spectator sport

By on

This might be the dumbest and most entertaining thing we've stumbled across in quite some time, and clearly we aren't alone in this opinion. Using color and spatial detection, two fancy goldfish challenge each other to games of Streetfighter II, and thousands of people turn out to watch it on Twitch. No joke.

Lionfish behavior may hunt species to local extinction

By on

Most predators will hunt where prey is most abundant. When prey is scarce, they will move on to new hunting grounds. Not lionfish! These trespassers are the worst house squatters ever. New research by OSU finds they will literally stay in one place and eat everything out of house and home.

Product Review: Products for 'Rapid Cycling' of Marine Aquaria: Brightwell Aquatics' MicroBacter7 and Continuum Aquatics' BacterGen.M

By Dana Riddle on Aug 20, 2014 at 09:00 AM

Two products were tested under controlled conditions for their abilities to consume/convert carbon and nitrogen-based compounds (referred to as "cycling" by many hobbyists.) Results suggest that, at dosages recommended by the manufacturers, these products contain sufficient numbers of carbon-cycling bacteria to properly inoculate biochemical oxygen demand tests, and ammonia-oxidizing bacteria are present in numbers that can "seed" a sterile environment, and perhaps hasten the aerobic portion of the nitrogen cycle along by a few days when used as a supplement to conventional seeding via live rock, live sand, and hardy "starter" fishes. Potential problems with over-dosing are also discussed.

Tenji redefines "dive bar" with 7,500 gallon custom aquarium

By on

A plant-less, coral-less aquarium isn't what we usually write about, but this unique build is a remarkable engineering achievement. And considering where it's located, it's probably a good idea it isn't filled with fussy livestock.

Pachyseris inattesa is a new Red Sea stony coral

By on

Pachyseris inattesa is the newest described species of 'elephant skin' coral. This new species has a smoother appearance than its congeners aquarists sometimes encounter. The best we can describe P.inattesa is a cross between Montipora verrucosa and Leptoseris sp. corals. (It's a good thing we have pictures!)

Might anti-anxiety medication help our fish?

By on

Benzodiazepine is a class of drugs commonly used to treat anxiety and sleep disorders in humans. But research is finding that this type of drug has a surprising effect on fish. It decreases the mortality of fish fry, makes fish bolder and more active, and feed with more vigor. Is psychoactive medication the next frontier for aquarists and breeders?
