The Barcelona Aquarium is one of the largest and most-renowned aquariums in the world. The aquarium is an incredibly popular tourist destination with over 1.5 million visitors per year, making it the 4th most visited place in Barcelona.


Located on the Moll d'Espanya at Port Vell, it is easily accessible by foot from the Old Town. Visitors to the Aquarium can check out over 450 different species in 35 different tanks and habitats.


I had a great time slowly walking round looking at all the fish. Here are the five species of saltwater fish in the Barcelona Aquarium that I found to be the most beautiful.


Longspine spinefish

Longspine spinefish (Macroramphosus scolopax)

The longspine spinefish is a species of fish found in the Atlantic, Indian, and west Pacific Oceans. The species has a long beak in the shape of a tube, with a small mouth with no teeth at the end, and is up to 18 cm (7 in) long.

Also known as bellowsfish, spine trumpet fish, or trumpetfish, these fish inhabit at depths of 40 to 300 m (131–984 ft). They swim slowly, often with the body vertical and the head down.



Yellow tang

The yellow tang, also known as the yellow surgeonfish or yellow Hawaiian tang, is a saltwater fish species found in the Indian Ocean and the Pacific between Hawaii and Japan. The habitat of this species is from inside the reef out to depths of 40 m (131 ft) or more.

This is a medium size fish, with an adult growing to a length of 15–20 cm (6–8 in). Because of its oval-shaped, vibrant yellow body, the yellow tang is one of the most popular fish in a saltwater aquarium. Its lifespan is 30 years in the wild and 10 years in captivity.



Royal dottyback

The royal dottyback, also known as the false gramma, bicolour dottyback, or two-tone dottyback, is a visually stunning species of fish found in the Indo-Pacific Ocean. They are usually seen hovering close to corals and rubble in shallow coastal reefs.

The fish features a half yellow and half purple body, and grows to 5–7 cm (2–3 in) long. Any aquarist will recognize the royal dottyback as an excellent aquatic pet to care for in their home aquarium.



Gray angelfish

Pomacanthus arcuatus
Gray angelfish (Pomacanthus arcuatus)

The gray angelfish, also called the Caribbean angelfish or black angelfish, is a species of large fish found on coral reefs of the western Atlantic Ocean, at depths ranging from 2 to 30 m (7–98 ft).

This angelfish may live up to 10 years. The maximum recorded length is 60 cm (24 in) and the maximum recorded weight 1.8 kg (4 lbs). These fish are curious and brave, and are a popular subject for underwater photographers.



Humbug damselfish

Dascyllus aruanus
Humbug damselfish (Dascyllus aruanus)

The humbug damselfish is a coral-dwelling fish found in groups sheltering in the arms of staghorn corals over shallow lagoons and inshore reef flats. Also known as three-striped damsel, white-tailed footballer, or zebra humbug, these fish range throughout much of the Indian and Pacific oceans and in the Red Sea.

Sporting three black stripes on a white body, the humbug damselfish has a zebralike appearance. It can grow to a size of 7–10 cm (3–4 in). The humbug damselfish is considered a good “starter” fish for beginning saltwater aquarists.

  3. I used to have a saltwater tank when I was a kid, and we actually had every single one of these fish (minus the Longspine spinefish). It's so peaceful watching them swim around.
