As predators become more adept at catching prey, the prey must find novel ways of evasion and predators that have not evolved the speed and agility posessed by their prey, they must find more stealthy methods of hunting. This has culminated in an amazing array of methods of camouflage and mimicry that has given aquarists and divers some beautiful and unusual organisms to look at.
Aquarists need to inspect their fish closely every day, for signs of impending health problems. It is much easier to resolve a problem when it first starts, than to attempt a drastic emergency treatment when the fish is close to dying.
Certainly, invertebrates experience mortality in captivity, but less is known about their natural longevity.
To tell the truth, if I've ever seen a fish look genuinely happy to see me, it would have to be a surgeon. Many of them really do remind me of little aquatic dogs with their attitudes and antics.
Press Release: California Academy of Sciences Becomes First Aquarium in US to Breed Dwarf Cuttlefish
Breeding program offers new opportunities to understand a little-studied species, and introduce the public to these fascinating creatures.
Hopefully, as the knowledge base grows, more easily raised species will be found and protocols will be added for harder species so that the foundation's list of captive-bred species available to hobbyists will continue to grow.
Even under the best conditions, only a small percent of the eggs ejected in a spawning event will actually get fertilized, and of those that do, maybe 5% will make it through metamorphosis, or even far fewer than that.
Gary Lindner and Russ Kikel at AmericanReef.com this month bring you another podcast, this one dealing with shark management at the Pittsburgh Zoo and PPG Aquarium..
Aquarists working with fish from this region are quickly struck with how similar some species from West Africa are to those from other regions, such as the tropical Western Atlantic and the Mediterranean.
While this discussion is by no means an exhaustive list of worthy species nor a complete guide for aquarium husbandry, it is hoped that the descriptions and images of the creatures herein featured arouse a greater interest in this highly rewarding art.
Various videographers document the amazing behavior of the cuttlefish. For more information about each video, visit the linked YouTube video.
The reward may well be a heightened appreciation for the diversity and adaptability of the plants and animals we so admire.
The Hawaiian flame fairy wrasse is an awesome aquarium fish.
Kenneth and others share their beautiful temperate tanks with our readers.

The results of these combined experiments indicated that elevated copper levels can cause accute mortality in flame angelfish and significantly reduce the reproductive performance of orchid dottyback broodstock. Therefore, the use of copper as a therapy for external parasites in these species is cautioned.
