Green balloon like growths

Question
QUESTION: Hi i have a 130ltr marine tank and i have these green balloon like things growing on my live rock some are like air/water filled elongated balloons and some are round with a crust like outer any idea what they are please? and are they harmful to my fish? i have yellow tailed damsels x 2 honey damsels x 2 harlequin goby x1 clown fish  x 2 a medium sized seahare and a red scallop.  all doing well.

ANSWER: hello angela,

Im not totally sure about this, maybe  alittle better description of the bubble/balloon thingies???

Could they be Green Bubble Algae???

These are kinda common, but, are not good to have in the tank... cause they grow fast and all over...

Typically, these are removed by hand... take out the rocks and scrape the green bubbles off, and put them in the freezer to kill them.. (to keep them from finding ther way into your local streams and oceans...

Please look up some images of 'Green Bubble Algae' to compare to yours and please let me know if they are a match...  Or, if not, maybe a better description, or pictures

IT might be easier for you to upload pics to my new forum at www.thelittleocean.com  as it lets you upload direct from your browser,  (or you can use www.photobucket.com)

There are other folks/members on www.thelittleocean.com who might be able to help also...

Please joing there and post something in the introductions section and we can continue the IS hunt


thanks


and good luck

QUESTION: Hi Bill thank you very much i looked up green bubble algae and you are absolutely right, so tomorrow i will spend the day getting it off my rock and i will do as you say and put it in the freezer to kill it.  Thank you very much for your help

Answer
you can place them into baggies and then freeze them


You can also try geting some EMERALD crabs... they have been known to chomp down some of the smaller ones


good luck
