what do you think the most aggressive trigger is?

This is the most aggressive of the three and has the most horror stories behind it. It's on the list for two reasons. First, many of the stories I have seen have been involving timid fish or the yellowtail was placed in first and established it's territory. Both are incorrect ways on how to introduce a damselfish. Second, the yellow-tail damsel is often mistaken as a "Baby Dory" by children and with it's hardiness can withstand a novice hobbyist or parent purchasing a "Dory" (AKA Blue Tang) for their children. I personally have recommend this fish to potential Blue Tang buyers along with a lot of education about the care and maintenance required to successfully keep saltwater fish. The suggestion was so common, that I actually was interviewed by the about my experience with this fish.

So I have outlined the three best damselfish. Now let's break down the best practices for adding a damsel to your tank
Just out of curiousity, what do you think the top 5 most aggressive saltwater fish (that are commonly availably for the aquarium) are

The best example of someone rushing things goes like this: They have the tank setup and running with water and equipment, maybe a couple pieces of live rock. They get impatient looking at an empty tank so they go to a big box chain store that sells saltwater fish and buy a damsel. This one act is their first three mistakes in one. Do not add damsels, they are very aggressive. Even when small they can easily dominate a tank of larger yet peaceful fish typical of a reef. Many get very large and most lose what decent coloration they have when small. Even in rare cases where you decide to add one, they should be the absolute last thing added so that EVERYTHING else can settle in before they are added (even then the odds that the other fish will last are almost nill). The third mistake here is not making sure that enough live rock has had enough time to cure and cycle the tank. A few days or at best one week later the damsel is still alive so they go back and get a handful of other, more reef typical fish. This may include a pair of clownfish, a couple firefish, a flame angel or coral beauty (or both, but they will fight each other), and many other options. he tore into his stomach and pull it out

Eels are one of the most fascinating and one of the most demanding species of saltwater fish kept by aquarists. They are characterized by their long, snake like bodies and scale-less, mucus covered bodies. Unlike most other species of fish, eels do not have separated dorsal, anal and caudal fins. Instead their fins merge together to create a continuous fin ridge along their bodies. Most species of eel are nocturnal and highly predatory. And due to their aggressive temperament should only be kept by experienced aquarists.Number three on the list are the , a favorite of many aquarists. Due to a combination of poor handling practices during capture and shipment, and high susceptibility to particular diseases, newly acquired specimens may succumb to ich and oodinium. Clownfish are not as hardy as the two previous families of fish, but if successfully acclimated to captivity they can be quite sturdy. The common (percula) clown, Amphiprion ocellaris, a favorite with saltwater aquarists, is unfortunately also the most delicate of the group. The larger species, such as the tomato clown, fire clown and sebae clown, are somewhat hardier. My choice is the tomato clown. This species maintains its color well in captvity and seems to do fine without an anemone to live in. They do grow somewhat larger than other clowns, sometimes exceeding 4 inches. Even at that size, however, they do not exhibit significant territorial aggression.One of the most challenging aspects of keeping saltwater eels in the aquarium is their extremely aggressive temperament. Most large species of eels are predatory and will quickly devour any species of fish that they can fit in their mouth. Therefore eels should only be kept with large, moderately aggressive tank mates that are able to hold their own ground. Aquarists should also take care when handling an eel aquarium as they can often bite the hands of their keepers when scared or when in a feeding frenzy.Each of the different types of saltwater fish you'll find in the hobby is adapted to life in the ocean in different ways. Despite the vast expanse of the oceans, most of these fish stay within a particular region. These fish are small ocean inhabitants, and often a food source for much larger marine animals.Most of the species live among reefs, rocks, and rubble strewn sandy areas in the wild. Their natural homes provide nooks and crannies where they can quickly take refuge if the need arises. These areas also support many other types of plant and animal life that are rich, nutritious foods sources for the fish. Some fish will swim about fairly large areas, while others stay very close to the same coral head or rocky outcropping their entire lives.There is competition in their natural habitat for both food and protective shelter, and so almost all saltwater fish have some level of aggression. Many will stake out a particular territory as their home and aggressively defend it from intruders. They identify intruders by the body shape and/or color of another fish, as well as by its eating habits.
