Hi,
Best place in my opinion would be InlandAquatic... I did not see the name Padena in the tons of macroalgae they offer but if I were you I would call them and explain my problem..
I am pretty sure they will know which algae you need.. I would say they must be the biggest distributors for macroalgae..
Heh, Padena sp. is NOT a green algae. It is brown and I don't think I've EVER seen it on an availability list. I have been seeing it, and/or close cousins from the Lobophora genus quite a bit lately on Fiji Live Rock. It is a brown encrusting calcareous algae.
I was able to identify it by refering to pages 112-116 of this book
Hi guys, I'm desperate looking for "Padena" macroalgae because I got a nudibrach that feeds on this kind of macroalgae only, in the sore they told me that he feeds on green algae but now I know that they lied to me and I don't want him to die, maybe someone know where can I buy macroalgae on the internet. Please help.
