Please ID and advice

Can anyone ID this green stem like things that appeared in my aquarium. I have about 5 of them now (started with just one appearing one day and growing).

Also, I am in need of some advice/suggestions for a supplement/ food to feed my coral. Any ideas? Is there something out there that is good for all types of soft corals?




This one is kinda blurry, but it gives you an idea

 

If it doesnt move around, most likely its some form of plant or microalgae. As far as the coral food, wow, theres so many different ones to choose from. I personaly use this;


and
twice a week. Theres also these that I used to use from Kent Marine

 

hard to say could be some type of spaghetti worm if it is though dont worry about it there just detritus feeders lunas probly right though usually very knowledgeable

 

It's a kind of macroalgae, most likely Neomeris annulata. The majority of reef keepers seem to like it, some claim it can become a pest.

Cheers,


Don

 

Becareful with adding liquid foods to your water as the can quickly deminish water quality! It depends on the type of corals as well, as most are symbiotic receiving most of its nutrients through the photosynthetic process as a result of the corals host zooxanthellae. Lipids, carbs and amino acids are manufactured through the corals ability to produce ammonium, that feeds the zooxanthellae. This aids in nutrients being provided for the coral.
Corals will also feed on disolved organics, nitrates and phosphates as will anemones and Tridacna clams, and various other filter feeders!
So, in conclusion, liquid foods are not needed, and by performing a weekly small water change, you are replenishing traces and vitamins that may be lost through fish respiration, carbon and skimming!
