The aquarium advises to avoid imported mahi-mahi harvested by long line, but rates troll and pole-and-line caught as a good alternative.

[28] They are estimated to live up to 100 years, based on analysis of annual growth marks on scales, and reach maturity around the age of 55; [ 29 ] the oldest known specimen was 84 years old at the time of its ...
Sarcopterygii (fleshy fin), members of which are known as lobe-finned fish, is a group of the bony fishes. Traditionally, it is a class or subclass that excludes Tetrapoda , a group of typically terrestrial vertebrates that descends from lobe-finned fish.
In fish, barbels can take the form of small, fleshy protrusions or long, cylindrical shaped extensions of the head of a fish. The cylindrical barbel shapes are built on an internal support system that can be made from ossified tissue or from cartilaginous connective tissue that provides a base for blood vessels and myelinated nerves to wrap ...
These fish have big, fleshy lips and tend to live on coral reefs in the Indo-Pacific in small groups or pairs. They will often associate with other fishes of similar species; several species of sweetlips sometimes swim together. They are usually seen in clusters in nooks and crannies or under overhangs.
Many color and tail pattern varieties exist. They generally need a ratio of 1 male to 2 females or more. All guppies and mollies are hardy fish that tolerate lower oxygen levels and temperatures than most aquarium fish, give birth to live young, and readily breed in home tanks. [58] can live in full sea water [59] 66 °F - 84 °F (19 °C - 29 °C)
The painted sweetlips has fleshy lips which increase in size as the fish matures. There are 6 pores on the chin but the median pit is absent. [3] The dorsal fin contains 9–10 spines and 22–25 soft rays while the anal fin contains 3 spines and 7 soft rays. [2]
Tropical fish is a term commonly used to refer to fish that are kept in heated aquariums. Freshwater tropical fish are more commonly kept than saltwater tropical fish due to the common availability of fresh water sources, such as tap water, whereas salt water is not commonly available and has to be recreated by using fresh water with sea salt additions.
