About George

I started this adventure almost 20 years ago when I set up my first saltwater tank.

George Mavrakis makes videos about aquariums. On CoralFish12g he takes the hobby on the road: public aquariums, fish farms, breeders, fish stores and markets from the Amazon to Seoul, Bali, Bangkok, Cairns and Denmark.

At home it is reef tanks, seahorses, octopuses, axolotls and a koi pond in the basement. His channel has 1.98 million subscribers and 428 videos; his Instagram, 693K followers.
