I have never had bubble coral in any of my tanks if that is what you are referring to. I took it out it was some sort of weird jelly consistency but I have no idea what it is. Maybe my eel threw up?
na, bubble algae is something different than a bubble coral. It might be something else, but it looks like some semi-poped dead bubble algae to me. Either way, i wouldnt be too concerned about it :)
Okay thanks, by the way aiptasia is dead for the most part I think it was because I rammed that syringe inside each of them, even though it didn't have a needle I think it worked they are gone from the area I sprayed. Thanks a lot for your help with the pesky things!
