However,... (more) Diane 2009-10-29 The Pale-tail Chromis or Yellowtail Blue Damsel displays typical damselfish behavior, very active and a great eater! A good fish for the beginner as it is hardy and inexpensive.This is a young specimen of the Pale-tail Chromis or Yellowtail Blue Damsel, about 1 inch long. Generally juveniles like this will be available from a marine fish store. As they mature, their tails loose the yellow and become white and the bright blues become a more bluish grey.

Maintenance difficulty:
The Pale-tail Chromis or Yellowtail Blue Damsel is among the
easiest of all marine fish to keep.
Maintenance:
This fish will readily eat all kinds of live, frozen, and
flake foods and algae. Finely chopped meaty foods (like brine shrimp)
can be fed regularly. It is best to feed small amounts several times a
day. In a reef situation they don't really need to be fed very often at
all.
Foods:
All kinds. See "maintenance" above.
Social Behaviors:
Like all damselfish, they can be territorial and aggressive,
especially as they get older. Can be kept together and with other larger
fish but watch them closely to be sure their aggression doesn't become
destructive.

Not Known.

No special requirements.

Some of the damselfish have been bred in captivity. See general
breeding techniques under Clownfish on the marine breeding page.

| My husband and I are new at the saltwater. After we got our tank set and waited till all was right w/the salt and such, we bought two of these lovely fish. However, after we put them in, we can't seem to find them anymore, we are confused as there are no other fish in the tank. Hope to see them soon.

| I've had my yellow tail damsel for almost a year now, it was the first fish in my tank. I've had fish come and go in my tank due to various reasons, but my yellow tail has held on thick and thin and is by far the hardiest fish I've ever had. However, he is aggressive with new fish, though only shortly after he "tells them he's boss". My damsel is cautious and loves swimming in and out of my rock. He is getting "lighter" in color as he gets older. This is a great fish starting out and isn't that aggressive.

| I have 2 clownfish and they're very cool. I also have a lot of other saltwater fish. My cat stickes her paw down in the aquarium because she thinks they are pretty, but she can never catch them.

| I have had saltwater fish for only 3 months now and my two fish are a yellowtail damsel and an ocellaris clownfish. My clownfish was mean and picked on the damsel, but now my damsel has gotten agressive and fights with my clown. A very active fish and they both like to pick at the live rock. They are a very pretty fish.

| Some of the coolest comments: |
| Damsels are good fish for the cycle process and are cute while they are young or juvenile. When they age, like people, they lose their vibrance and become a little more cranky. I house 2 of them now, a yellowtail and a velvet in a 55 gallon reef tank. I was going to trade or sell the damsels after the cycle process was completed but I noticed them eating algae off the rocks in between the zoas and the paly's that the turbo snails can't get at so I am thinking now that I may keep them around. Typically they hate anything new in their space but mine seem oddly docile...they don't attack other fish, even new tank mates. They do go after the snails and my hermit crabs but I can't tell if it is an aggressive lunge or if they are eating off the shells. It appears as though they are just picking stuff off the shells.

| Just to update... I added a new few new fish and the little yellow tail damsel went at them like a parana while ignoring pre-existing fish. I quickly removed the yellow tail from the tank and moved around the rocks. Then put the yellow tail back in thinking he was in a new tank. Since he was last in once again, no problem. I recommend adding yellow tails last or to remove and re-arrange, then put back in after new fish. Mine leaves pre-existing fish alone. 2006-02-05 |
