I have a 29gal biocube and its about 7 months old now, I've gone through so many different algae problems - its always one after another >.< And I've gotten pretty good at identifying and taking care of any nuisances via water changes, food schedule changes, light schedule changes... Everything has been in the clear for about two months now, until I noticed these clear things. Are they eggs? Are they algae? Are they just really weird air bubbles? is it an anemone? Is it aiptasia? I've tried looking up everything to no avail... Does anyone have any ideas???

Tunicates, I think? If so they are harmless. Google for a match.

Well thats good to hear! Can I keep them or will they grow all over and cause problems do you think?
