Another possible downside? The accidental release of nonnative species. “It’s crucial to reduce the demand for wild-caught tropical aquarium fish, as well as to move away from more destructive collection practices,” says Nicholas Whipps, a legal fellow at the Arizona-based Center for Biological Diversity, an environmental protection organization. “But it matters how captive breeding might be done in the future."
It is many aquarists' dream to successfully breed fish at home
As the owner of Pacific Planktronics on the west side of the Big Island in Hawaii, Kraul has also become a focal point of a small that raises popular species of tropical fish through captive breeding, similar to the way many freshwater fish are raised for life in aquariums.

There are quite a few species of Pseudochromis that are now available in the aquarium industry, and the orchid dottyback has certainly become one of the most popular options. This vibrantly violet member of the Pseudochrimodae family hails from only one marine habitat on the planet: the Red Sea. They also tend to live in fairly deep water in colonies along ledges and vertical walls, all of which are habitat conditions that make them difficult to collect. They have regularly been collected at depths exceeding 150 feet. Consequently, these fish used to be available only sporadically and infrequently, and they would demand prices upward of $90 in the United States. Thanks to captive-breeding efforts, they are now fairly easy to find and are no longer so expensive. The replacement of expensive, wild-caught P. fridmani with their affordable tank-bred counterpart, proves just how important it is to support breeding efforts in our hobby.
