Han Solo Posted December 8, 2014 Share Posted December 8, 2014 At first sight you can see a lot of tiny flatworms around that area, maybe it's eggs I thought. But some further research lead me to thinking the macroalgae has gone "sexual" but I didn't find much information on how that truly effects the tank. My refugium light is lit 1/2 day opposite the tank lights. Any ideas? Kill it with fire? Link to comment
rnmike Posted December 8, 2014 Share Posted December 8, 2014 Looks like your fuge puked! Gross! Link to comment
Weasel Baron Posted December 8, 2014 Share Posted December 8, 2014 scraping it off may make it worse... are you sure its the macro? the lack of color/chloroplasts has me thinking it may be a sponge or tunicate, or even a weird sessile form of a sea salp check the pic Link to comment

The webbing that it is all in is very characteristic and looks to be spreading directly from that macroalgae the bottom. The algae itself is covered in white mossy looking stuff, that looks like what happens when macro algae goes "sexual". Hmm? Do you think it is bad enough to remove? I tunicate would be cool though. There are also a ton of flatworms (along with a ton of copepods) and I since I haven't heard much about flatworms would those be deemed safe? Only have seen a few on occasion on the main tank coming out of the sand. Link to comment
Weasel Baron Posted December 8, 2014 Share Posted December 8, 2014 the flatworms are likely Amphiscolops, and harmless, but keep an eye out for dead patches on your coral the more I look at the first pic the more I think colonial tunicate, the siphon is likely facing outward towards the inside of the tank, you can even see them on the individuals on the upper right side of the branch. I dont think its a change in your macro; even when they go to sexual reproduction its just a release of spores, not a massive change in body plan tunicates are harmless. its a cool hitchiker in my opinion, and in your fuge so you dont have to worry about obscuring the view!

Han Solo Posted December 8, 2014 Author Share Posted December 8, 2014 Awesome, thanks for the info!. Do you think the more milky white strands around the red macoalgea are something else? Link to comment
Weasel Baron Posted December 8, 2014 Share Posted December 8, 2014 couldnt say definitively. could be sponge, could be part of the growth on the glass, could be new growth for the macro Link to comment
