I would like to get some additional Halimeda incrassata for my macro-only tank... Originally got it from Petco, but now "out of stock" (January). Is this a seasonal thing or more random? I couldn't find other sources right now of that exact Halimeda. I need this species specifically because I have some Elysia tuca that came with it and now laid eggs. and I may need to feed the babies on the same exact Halimeda! My original Halimeda may be dying slowly and getting covered with red string algae, so I would prefer fresh healthy stock soon. Any advice appreciated.
