Is this a Thorea algae?

Looks like a dead black worm, often sold as blood worms at fish stores. I used to feed my fish live black worms and after sitting in my fridge for a few days some would die and turn a cream color just like that. But then again I've never heard of thorea algae.

 

Dead Things I Am Thinking...Reginald James is Right

Hi Peter,

Frankly, it looks like worms, dead or otherwise to me as well.:gw

Thorea, the freshwater species tend to be dark green.

Pick some up and crush it between your fingers,:eek-new: you should be able to tell whether it is meat or vegetable.

If it seems “vegetable,” cut across the filament and with, a good magnifying glass it should look like the top picture here, click the picture to enlarge.

I know I have a better picture somewhere, I just cannot locate it, but even though that is not one of the tropical species, it gives a good representation.

If Those Are Pictures of Your Algae, You May Have A real Find

Hi Peter,

Where do those photos come from? Did you take them?

If those are pictures from your tank, try to preserve the algae.:gw

What is the water temperature?

Told You Bio Is Nuts; Point to Algae, Bio Says "Part of My Collection." Yeah Right!

Hi Peter,

I am one of those folks that really find algae fascinating; I have a bit of a collection (intentional) going.

Obviously, I am a rank amateur but your photo from post #4 looks to me like it may be an endangered Serbian species, which would make it rare and perhaps illegal to possess.

It is hard enough for people who know what they are doing to make identifications from photographs, so a clumsy amateur as I cannot be at all sure.
