The title says it all. If you are interested in purchasing damsels, prepare to have a pack of drama queens on your hands. While damsel fish are quite cute in their juvenile stage (see photo), they aren’t quite as pretty as adults. Let’s learn a bit more about these temperamental fishies.
Dascyllus albisilla (Hawaiian damsels) and Dascyllus trimaculatus (Indo-Pacific damsels) are often mistaken for each other, but have a few differences. Possibly the most notable is the fact that the Indo Pacific damsels have white spots that are about the same size as their eye, while the Hawaiian species features larger spots. These aren’t the only names for these black and white beauties however. This species of damsel is sometimes known as the Hawaiian dascyllus, Domino damsel, or White Spotted damsel.
Many think that Domino damsels are a cute and quirky addition to their salt water aquarium. They are right, in the beginning. But, much like all damsels out there, these fish can become demanding and rather bratty over time. This is because adult damsels are extremely territorial, a trait that isn’t shown in juveniles. Also, when they reach adulthood, these damsels get seriously ugly. There, I said it, it’s out! They have commonly blue/silver scales an are pretty unremarkable. Damsels are about 5 inches long at adulthood.
To explain the territorial behavior of Domino damsels, it is important to understand their mating patterns. Damsel fish actually nest and lay eggs, and are fiercely protective of their nesting area throughout the year. You may notice a faint humming sound as you are cleaning your tank every once in a while. This very well could be your Domino damsels. They are known to make a purring noise when agitated.
So, what’s my opinion on these popular salt water fish? Ehh, you can take them or leave them (this isn’t politically correct, and I’ll probably get a very angry message from PETA, but I’d personally keep them til they weren’t cute anymore, then flush these little fishies!).
