It is almost inevitable that people will pick “the pretty ones” out of the bunch. Many popular ornamental species/cultivars (koi, decorative maize, etc.) originated as farmed food species. We certainly may be seeing the same at this time with certain types of macroalgae in the marine aquarium hobby.
We now have long-finned clownfish. Already. It is not hard to imagine that in the coming years we could see a good many varieties of “domesticated” ornamental marine algae. These seaweeds will be cultivated (and perhaps even selectively bred) specifically for their aesthetic value. At least for now, we will have to be satisfied (and certainly should be) with the numerous forms (and even species) that have just reached the aquarium trade in more recent times.
Many, if not most, aquarists initially acquire macroalgae as a means of reducing excess dissolved nutrients (thereby controlling nuisance algae). Accustomed to the generally modest growth rates of aquarium animals (e.g. corals and clams), some reef aquarists are astounded by the sometimes very rapid growth of macros such as Ulva and some Gracilaria. Perhaps some even used Caulerpa “back in the day” and just forgot how prolific this stuff can be.
There most definitely is something satisfying about such clear success and such instant gratification. And emboldening… Given the relative ease which he or she cultivated other macroalgae species, an aquarist could feel justifiably confident in trying newer, more exotic types.
“Exotic?” Really? Macroalgae? Absolutely. It’s really about their desirability and their supply. As it is, many are in very low supply. This is for two reasons. First, growers tend to focus on the made-for-the-fuge “nutrient sponge” types because hey, that’s where the strongest demand has been. But another reason that ornamentals often get overlooked by producers is because they tend to be a little more difficult to grow and/or grow at considerably slower rates.
But we like pretty stuff, do we not? That is certainly so with aquarists. And, over time, demand for truly ornamental macroalgae has risen considerably. This has occurred along with an overall growing interest in marine botany. The result is the emergence of premium specimens in boutique stores. Now, curiously, very small pieces of select macro species are sometimes offered much like coral frags, meticulously mounted on plugs! And indeed, offered at select prices.
Three Awesome and Unusual Macros to Look Out For
Perhaps you are interested in setting up a refugium, mainly for the purpose of cultivating ornamental species and creating a marine garden display tank. You might have had a planted refugium (full of utilitarian types such as Chaetomorpha) running for quite some time and are eager for a little more variety of color and form.
We here suggest a few rarities that can be obtained at AlgaeBarn. As the originators of the “clean” macroalgae for marine aquaria, you can be sure, first of all, that these products are highly unlikely to carry pests or diseases such as Aiptasia, Cryptocaryon (marine ich), etc. Also, considering the generous portion sizes offered, you can stock a refugium densely and beautifully without breaking the bank.
Now, we really mean “to look for” here. These species/varieties require more care during production, and are in high demand when they appear, so some types are of only limited availability. This is certainly the case with our three selections. But they do appear often and should definitely be looked at; get them while you can!
- Dragon’s tongue (Halymenia dilitata)Dragon’s tongue is prized by reef aquarists as an ornamental macro because of its bright red coloration and deeply furcated, flame-shaped fronds. It is pink to deep red in color. This beauty occurs throughout the Gulf of Mexico, the Caribbean, and the Tropical Atlantic Ocean. It favors rocky subtidal (usually reef-associated) environments. Unlike some other red algae, this species loves strong water currents. It grows either free-floating or attached to rocks. When attached, it can grow to heights of over 1.5 feet. Still, its growth rates are rather slow. Thus, it requires less frequent harvest than other macroalgae. It requires good water quality and good water movement for optimal health. It tolerates lower light conditions and therefore can flourish in shadier or deeper parts of the tank. Finally, it is extremely palatable and useful as a nutritious food for many herbivores.
- Leafy Sphere (Halymenia maculata)Leafy sphere macroalgae is beautiful enough for use right in the main tank, provided it doesn’t house large herbivores. It is pink to purple to deep red in color. It is distinguished from its cousins (e.g. Gracilaria) in its thick blades which are broader and more rigid. Halymenia maculata occurs across the Western Pacific and Indian Oceans in rocky, reef-associated, subtidal environments. Like H. dilitata, it favors areas of moderate to high water flow. It grows either attached to rock or free-floating. Because it grows slowly, it requires harvesting less frequently than some other macroalgae. It loves good water quality and strong water movement. It tolerates lower light levels. It makes a great food (when harvested from the refugium) for herbivores such as tangs, rabbitfish, angelfish, etc.
- Thick Ogo (Gracilaria sp.)The thick red ogo Gracilaria plant is an exceptionally beautiful macro. From bright red to burgundy in color and sporting thick, flashy fronds, it adds a dash of color and texture to any refugium or saltwater aquarium. Thick Ogo is somewhat faster growing than the above examples and is quite hardy under usual conditions. This makes it a bit of a showy compromise, as it is attractive but also fairly good for nutrient export. Like the above examples, in addition to its good looks, it serves as a great live food for your hungry herbivores.

All my dragons breath got eaten. Oops
Will order dragons tongue when back in stock
Benjamin Hosaflook says
As weird as it may seem, i think certain macroalgae look pretty cool! I know some friends who are even planning on doing a macro algae display tank!
Unfortunately they are both beautiful, and tasty! I have found that so far nobody is eating my leafy ogo in my tank, it seems to be doing well under standard tank lighting (not in my refugium) and nobody wants to touch it. Although I will say my urchin is currently wearing it and walking it around the tank!
Vanessa Ruiz says
I use cheatomorpha in my aquarium for exess nutrients ect.. this was a very interesting blog
Vanessa Ruiz says
I tried to leave another comment however it wouldn’t let me , it kept saying I left a similar comment (lol user error?). Any way very interesting blog , I plan on learning more about this seeing as I use macro for nurient export already
Christopher Mains says
My Mandarin is getting fat!
Great to hear Christopher. I am sorry your sea lettuce didn’t make it, but we would really love it if you would reach out to us ( [email protected]) and we will take care of you!
I’m learning so much, thanks.
Love your blog posts, so informative
Always informative. Brilliant.
Had no idea there was premium macro
Robert OToole says
Cannot wait to try this!
Great blog. Thanks for the extra info!
Tanya Bazaldua says
I love using macro algae in my refugium. I will be adding dragons tongue.
I prefer dragon’s breath to dragon’s tongue but overall, I do find it difficult to get the yellow to shine through on the ends like fire. I ramp up the lights and no change. I wonder what the secret is.
We have learned that its a number of trace elements in the water (iron, iodide, etc) that help those colors really peak!

Using macros have improved my aquarium health tremendously
Steve Baring says
I would like to try these macro algaes.
SEAN PAGE says
I would love to grow some form of seaweed in my tank. Something that looks organic. Every time I plan something just about every herbivore my tank goes to town on it within a couple of days, then POOF it’s gone!
NICOLE GROFF says
If you have a sump you can easily do sea lettuce or just get a small tank lights and ghost feed
Kris Kasarda says
Gread read. Thank you.
They are great I have done waiting on them to grow

Nice blog. Interested in learning more.
Jonathan Ellis says
Great information. Interested in learning more.
I love the idea of having a variety of macro algae in my display tank. I think they all look nice and I’m sure the fish like the extra hiding places. Not to mention the nutrient export. I want to add some more types to my tank. The ones mentioned here sound like a good fit.
Jennifer Mumbower says
have to try..

A planted tank with a nice aquascape, with the right inhabitants, cool corals in accordance. It got to be a jaw dropping Display Tank.
Travis oglesbee says
Interesting. I just use your cheato
Robert Parker says
Fish are hungry
Josh Hiltabiddle says
Can’t wait to get my pods and phyto!
Eventually hope to snag some of these when they aren’t sold out! Will keep looking
Malachi Inabnit says
In the hobby nowadays so many people go for Coral, I had no idea there was so much interesting algae to be had out there.
Kyle watts says
Izaac Ubelhor says
Looks like it’s time for some thick red ogo
what do you recommend for an ornamental for the reef tank that’s also good for nutrient absorption but not palatable for the fish.
Jeremy butwina says
This is a great read thanks guys!
Leslie Pustilnik says
I would love for my fuge to be more attractive with additional types of macroalgae
William Smithee says
I currently only use chaeto. Perhaps I should try something else in addition to the chaeto.
Rhonda Swetnam says
This is exciting news! Can’t wait to try them!
Bryan Pierre says
Jonathan Pinero says
This is great material.
Great info on algae
I love the look of exotics, but they are frequently outgrown by the other, faster growing, and hardier Macroalgae. Also, being hidden in a ‘fuge they don’t shine like you’d like for the cost.
Nicole Radice says
I think all my cheato is dead. I’ve been wanting dragons breath
I love these blog posts!! So much great information
Ben Wehmann says
Christopher Burns says
makes you think
Judi A Knight-Mitzel says
Which of these would be more suitable for a 32 g biocube and easily contained? Appears Dragor or Leafy would be better of the 3 but I am nervous of trying a macro in main display tank after previous (many yrs ago) having a macro all but take over a 14g bio. Thoughts?
Justin Grove says
I’d love a years supply of PODS!!!!
I am always looking for more information on algae’s and their use in the fish tank! This is more fun than growing a flower garden!
Will definitely be ordering dragon tongue soon!
Rose Dutka says
I’m wondering which of these are best for a seahorse tank?
Just started a refugium can’t wait to see how it works out
