#ed_op#DIV#ed_cl#Well being that I dotn know what Hydra are, and to me they look like very small feather dusters im gona go with the dusters, and the green bubles in bubble algae, I may be wrong but I've been told to remove them and dont let the burst, If what I was told is right than they hold nitrates and well give you a small nitrate spike, But I would wait for someone else more experanced to explain those to yeah!#ed_op#/DIV#ed_cl#

Hydra are pretty small I beleive the last one I saw was with a magnafing glass or microscope

#ed_op#DIV#ed_cl#ok. I dont think they are hydra. They look like a small stick polyp. Also the green balls are bubble alge. They are BAD. Hydra are more of a red mound, not sticks. Hope this helped.#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#Wait for some one more experianced to give you a more deffinite answer!#ed_op#/DIV#ed_cl#

#ed_op#DIV#ed_cl#I also believe that the "coral" is a fine finger leather. It is hard to tell cause the pic is streched out but its that or a devils hand.#ed_op#/DIV#ed_cl#

your coral is a finger coral. and your feather dusters are fine they will sprout up. my tank is covered in them, my copperband loves them and the green thing is bubble algae those are something you want to try and avoid popping if you do they release into the water and they will spread quite quickly. just keep an eye on them I had them and they took care of them selves.

#ed_op#DIV#ed_cl#so what should i do with the green alage balls? i mean how should i remove them without letting them pop? should i take the rock out of the tank and remove them with like a knif? The only problem is that my coral is connected to the rock. Or should i just let them be? what will make them go away?#ed_op#/DIV#ed_cl#

#ed_op#DIV#ed_cl#Keep your eye one them, they might multiply but alot of the time they will just dissapear!#ed_op#/DIV#ed_cl#

[Lifeguard50020042005]

#ed_op#DIV#ed_cl#well what do i do if they multiply?#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl#

you can pop them just have a siphon going and suck them up when they pop. and you should be allright.

[graphixx]

your algae is a Valonia they are among the largest known single celled plants, each bubble is a single cell. so when you pop them and let them float in the colum all of the nuclear matereial scatters through the tank and this is how they spread. They are only controlled by removal. reducing nutrient levels in the tank does not affect them. they are actually pretty neat. they get their nutrients from the activity of worms, crustaceans, and other small fauna living beneath them.
