Algae ID?

jmustapha · 12/12/2013, 01:40 AM

Hey guys. Does anyone know what this stuff is? I'm new to hobby only 2 months in and have this stuff growing on the underside of rocks everywhere

Thanks

They look like white Foraminiferans, but I can't be 100% sure from the picture. If they are, you're in good shape because they are actually protozoans as opposed to algae.

I'm not 100% sure either on the ID, but this article did come to mind first.

Um, we didn't answer your questions? Did you do a search on Foraminiferans and compare it to what is in your tank?

I have those all over my tank - I thought they were hydroids.

Nope, they aren't hydroids. These are Hydroids.

Well, there are many, many types of hydroids and some do look similar to the OP's pic. Could be Bryozoans or Forams too - would need a better pic. See here: http://www.chucksaddiction.com/hitchodds.html
