A great alga for the Marine Tank Display, where it will become surely fast a highlight and it might compete when it comes to the beauty of it with a lot of marine corals.

Gracilaria Curtissae Marine Macro Algae

This colour of the Gracilaria Curtissae algae will vary depending on the light its get. It will become darker when it gets less light, and brighter when it gets more light.


Herbivore marine fishes love to nip on this macroalgae. Therefore it will be better to keep this marine alga in a safe place, for example in the refugium, until you like to offer it as additional food to your fishes.

As Gracilaria Curtissae won't easily attach itself it can be easily glued ( we use thick cyanoacrylate super glue ) to rock where you like to have it, or just place it in between your rockwork and it will attach itself after a few weeks.

Like for most marine macroalgae a higher level of Nitrate and Phosphate, in addition to the supplement of Iron, Magnesium and Trace elements will improve the growth of this macro algae.

Please note
Our macro algae are from fish free macro algae tanks, although we use sometimes pictures for demonstration purposes only which will include fishes, seahorses and or corals. 
We do our best to quarantine, treat and remove any unwanted hitchhikers, parasites etc from our macro algae but we can not guarantee that the algae are completely free of anything unwanted, not limited to Copepods, Rotifers etc. This is simply because that sometimes eggs, spores, etc can remain viable but not visible and hitchhikers can still stay hidden, especially in dense algae structures, despite our strict quarantine efforts. 

All macro algae will be thoroughly dipped in a professional solution to deactivate hitchhikers as good as possible before posting. If you don't want this, please send us a message together with your order.

We highly recommend nonetheless that you properly quarantine anything new before adding it to your marine tank.

We aim to offer you the healthiest and best quality macro algae on the market, therefore, all of our macro algae comes with a 100% Satisfaction Guarantee.

Every time i i cut it back it just keeps on growing.Can you please suggest anything that will eat it ?my tank is 4ft x2ft x 2ft ...250l. p.s. i live in South Wales but i live long Leeds fan and have driven up and down Elland rd many times,so where are you situtaed on Elland rd? Next time im up there for rthe football ill pop in and take a look. many thanks Ian


Hi. That is quite very uncommon. The Gracilaria species we have is not invasive at all, and we keep it for years without any problems. Could you please send us two pictures of the algae in your tank, with one macro shot of, if possible? Let's see how we can help you with this. Kind regards
