The beginner saltwater fish enthusiast has entered a saltwater aquarium hobby which is like no other hobby. It will be difficult to resist the temptation to pile in the most exotic of the saltwater fish species, such as most angelfish, anthias, butterflyfish, lionfish, wrasses, etc. But the beginning saltwater aquarist really should avoid these species, which are relatively fragile. The last thing you want is to spend a lot of time and money setting up your aquarium, only to have your fish sick and dying within a couple of weeks or months. Far better to start slowly, populate with hardier species, and get the hang of maintaining the appropriate marine environment with a group of aquatic pets that can survive your mistakes.

A few good beginner saltwater fish speciies that you can consider are damsels and chromis, basslets, dottybacks, pseudochromis, certain clownfish (preferably captive-bred), blennies, gobies, cardinalfish, hawkfish, among others.

The beginner should probably avoid most angel fish, butterflies, certain tangs (surgeonfish), pipefish, filefish and seahorses.

Any type of larger fish species or carnivorous type might well be put on the "later" list as well, until you have a bit more experience with the smaller guys. Also keep in mind that certain species simply don't get along with others (or even others just like themselves).

Eventually, these more exotic saltwater fish will be within your reach, along with that 100+ gallon tank and all of the state-of-the-art accessories. But for now, take your time, and have lots of fun as the incredible world of saltwater aquariums begins to come alive under your patience and guidance.
