Yellowtail Blue Damsel

Yellowtail Blue Damsel

The Yellowtail Damsel is not only an amazing coloured fish that adds a lot of presence to any tank, especially in groups, but is also a very hardy and easy to care for species. its colouration amazes many, as it holds a very vibrant electric blue body with a stunning yellow tail, which really stands out in all aquarium environments. Additionally, this fish is not as aggressive as some others in its family, and is extremely hardy and easy to care for which makes it a great beginner fish.

In order to keep this fish happy, it must be held in an aquarium of at least 40 litres with live rock, so it can hide between live rock when threatened. It also has a good temperament towards other fish, however when housed with more of the same species, it can become aggressive towards them. 

This fish is not only hardy fish but it is also reef safe and will not harm any clean up crew members. If you are only just starting out in this hobby, this should definitely be on the list of your first fish to add. 

This fish will thrive on a variety of meaty, herbivore, and flaked foods.

  1. Hardy as all get out! Very good eaters, even right after acclimation. They are VERY territorial and my 2 make the “cyclone dance” often. Larger tanks and plenty of space recommended. Will wag their tails in aggression/territorialism with your more peaceful fish and inverts. Incredibly beautiful.

  2. I bought one to cycle my tank and he hasn’t died yet! The blue isn’t quite as brilliant as the bluedevil’s (but almost) but makes up for this with the yellow tail. Mine is very passive, runs from a bluedevil, and doesn’t give the chromis a second glance. I definately recommend this fish
