All Comments: Yellowtail Blue Damsel

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.

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. Conserve the reefs..propagate your corals.

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.

Hi I'm new to this but am looking for a bit of help and support. I have two clowns, one lyretail anthias, and plenty of cleaners. Just added two little yellow tail's, and have seen most of the traits others have mentioned so far. Only two thing I'd appreciate help with. Hope it's pecking order, but it's the lyretail anthias that's bullying the yellow tails? 2nd: are these known to get White spot, out of my depth with this, one just has little White speck near his rear fin? Any help?

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.

Our yellow tail killed our chocolate chip star fish.

My two new damsels are just the cutest. They are so bold they come right up to the glass and taunt my schnauzer, then swim away, he is totally under their spell. This is my first marine fish. I didn't know that fish could have such great personalities.

Reading all this, I think mine's broken :/. He sits under the live rock in the little cave. Granted I only got him today, so he could be a little stressed still. I'll keep an eye on him.

I just got one and I love this fish. It has so much personality! It explores the whole tank and LOVES to eat!

This is a very good fish for beginners! I have 2 of these yellow-tailed damsels. they swim all around the aquarium and they love to hide in the caves of the live rock.

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.

I found they have lots of personality!!! They are very bold and will taunt the larger fish with an aggressive posture to say thats my rock! More posture than bite. Yes they are selfish but in a very cute way. Medium aggressive compared to other damsels and mine are doing great in community tanks. They will tend to hang in the back of the tank or at the bottom. They really have cute bold personalities especially when they are small. When very small they are all attitude and no bite until they grow a bit. Mine are still under 3 inches so I don't know yet if they will become mean.

I just got my yellow-Tailed damsel and he seems to hid under the live rock and he usually says close to the bottom when he emerges from underneath the live rock.

This fish is territorial but not too agressive. The one I have, likes to hide behind live rock, and will only comeout if my other fish come close to his territory. I will keep him for now.

I really dont like this fish, yes true, he was territorial and aggressive, especially he loved to attack other fish smaller than him, and every time I adding new small fish. What i can called this fish is SELFISH!

These fish mostly swim at the top of the aquarium
