Damsels - The Good, The Bad, And the Ugly

Ever since the beginning of our hobby, I have felt that more people start with a damselfish as thir first fish in the tank than any other fish. Why? Damsels are hardy, inexpensive and widely available. Throughout the years, I have seen this fish cause more stress and more "why the heck did I buy this thing?!" reactions from aquarists, mostly because the cute fish they bought for there tank is killing everything else they try to introduce. This has lead to the common stereotypical vision about damsels as viscious and unsuitable for reef setups. This is not true, in fact, some damsels make great reef fish. Since this is the New to the Hobby forum, I think I will include my views on Damselfishes to prevent newbies from making any mistakes when it comes to the time they have to purchase their first fish. I think the most common mistake newbies make when buying their first fish is not researching the species, and in effect buying a fish not suited for their aquarium, and later, suffering as a result. So here is a basic guide of the Damselfishes commonly seen in LFS's to prevent newbies from making that painful mistake. This is just a basic guide, be aware that fish have different personalities and in an otherwise peaceful species, some odd fish is going to be a hellion. It's nature.




The Good


Talbot's Damselfish
(Chrysiptera talboti)

These are one of the most peaceful damsels in the aquarium trade. They are as hardy as any other damsel, but they are usually well behaved and are not viscious like some of their cousins. They also exhibit a beautiful peach-like colouration.

Chromis
(Chromis sp.)

These are great first fish. They are relatively peaceful and are social, and should be kept in groups. The best number is 3. They exhibit some awesome colouration, especially the Blue Chromis, Chromis cyanea. They are great reef fish and will seldom bother anything.

Yellowtailed Damselfish
(Chrysiptera parasema)

These are a hit or miss. I have classified them as "good" because I have one in my reef and she is extremely peaceful and doesn't bother anything. She is my oldest fish and my first ever saltwater fish. Try to get a smaller specimen which doesn't show much agression in the dealer's tank.



The Bad



3 Stripe, Domino and other Dascyllus
(Dascyllus species)

These are the ones most people get as first fish. They are incredibly cute and round, and have nice colouration to boot. The drawback? The are extremely territorial to anything. They can stress out and even kill fish 4 times their own size. When small, they are bright and cute. When half a foot in length, they are drab and ugly. The bottom line: Stay away. Far away.

Blue Devils
(Chrysiptera cyanea)

They aren't called devils for nothing. This is an aggressive territorial species, but not as aggressive as dascyllus and may be kept with semi-aggressive fish. Some people have them in reefs with no relative problems, but most people don't. They will stress out gobies, firefish, and other small fish. Best kept in reef tanks with Dwarf angels, Hawkfish, Tangs, and other fish that can hold their own. Makes a good addition to the FO or FOWLR tank, as long as tankmates don't look at it as prey.

Giant Damsels
(Microspathodon species)

These look stunning when they are juveniles. They're even called "Jewel Damsels" in pet stores. But, be warned. They get a foot long and have temper to match. only attemot to keep this if you have an enourmous tank and the tankmates are big and aggressive. Even then the giant damsels may stress them out. For newbies, it's generally smart to stay away from these.



The Ugly




Jewel, Velvet, Javanese,Blue Fin, and Cross's Damsels
(Neoglyphidodon species)

These damsels can be a disappointment to newbies. When they are small, they have stunning, neon, extremely bright colouration. Once they get larger, The lose that colouration and become brown. They are quite aggressive and will do best in Semi-Agrressive to aggressive reef or FOWLR tanks. I currently have a Behn's Damselfish in my reef, and he is small and relatively easygoing, but we will see how he will be when he grows up.



Keep in mind that I have included the most commonly encountered damsels, there are still other damsels such as Pomacentrus. Here I have listed the best and the worst. Anything else is in-between. I hope I have helped steer people new to the wonderful hobby of saltwater aquariums in the right direction to avoid the stress of owning an aggressive, unwanted damsel. I also hopefully brought some releif to the damsels so less of them have to endure the stress of being extracted from a reef. Remember, it's never the damsels fault! :D


Happy Reefing!

The velvet damsel is extremely territorial and will also turn a blackish-brown colour with age. They are commonly known as Javanese Damsels. The golden damsels are less aggressive but are extremely territorial. :D
 
I had a Dascyllus in my 75 gal reef tank that taunted all my other fish. I had set a new group of frags in my tank one mornig and when I returned in the afternoon he had knocked them all over. This was the last straw. I had to tear half the tank apart that night but finally caught him. Later that evening you could see ihim in a ten gallon adoption tank at the local Petco. He got what he deserved!
 
I hate damsels, I think they are hardy fish and can handle almost anything, but I wouldn't buy them again... my personal opion
 
I can't even catch the little boogers for the life of me without takeing my live rock apart... still trying to though
 
nice informative post... but from IME i would move the yellow tail back to the bad... killed my baby regal tang... :(
 
i had a blue fin damsel, these guys should be put into the bad column, mine would swim from one side of the tank to the other just to nip at another fish
 
Blue fins are terrors. I put them in the Ugly column only because they turn black when they get larger. I have a friend who's bluefin killed a Niger Trigger.
 
I'm not good with names yet, but I have a all blue one, a grey one, and a black and white striped one, I think he is called a Humbug Dascyllus other wise know as a striped damselfish
 
you'll never get them out, I'm still trying to catch mine off guard to get them out of their... My anemone almost helped me once when the fish was stupid enough to go near it... lol but got away
 
The Chromis are some of the better Damsels.

The Blue-Green Chromis.

The Black-Axil Chromis.

The Neon Blue Chromis.

The like to be kept in groups of AT LEAST 3, the more the better in most cases.

I wonder if anyone has kept a damsel-only tank. They are pretty fish.

I think my biggest achievement in this hobby was netting (netting!) a yellow-tailed damsel without taking down any rock, corals, etc. All within 5 minutes.

TOP THAT! :bum:
 
I can't I've been trying for a few days tell I got tires of doing it, but I'm going to get them one night when its dar kand everything is off... maybe that will work...

I used to have a male yellowtail that got aggressive, I chased him into a rock and took the rock out of the tank. I returned him to my LFS. I still have the Female Yellowtail though, she's not aggressive at all. Good luck getting your damsels out of the tank bjonesjr1.
