Here is the latest unknown organism to show up in a crayfish tank. I have no idea what it is. Don't even'know the phylum! The central mass is about 1 mm in diameter; including the mushroom like appendages, it's 2mm. They occur on the glass and on the crayfish. Any ideas?

More inland here in Wisconsin, we find nothing like this in our tanks

Also posted on www.nanfa.org, where I got an answer. It is a protozoan in the genus Stentor. Read more here: http://en.wikipedia.org/wiki/Stentor_(protozoa). Very interesting that it's a single-celled animal.

You sure get some interesting things. That one looks like something playing a whole bunch trombones.


Or even a blown glass sculpture.

Harmless? And how fast does it multiply (regenerate)? Any benefit having them (it) ? Interesting reading, btw.

wtf lol. God be with u...

Seems to be just a filter feeder. I guess it's harmless.

ah, I just read up on stentors, you picture is a picture of a colony of stentors, each tentacle is one anchored down.

Dan, eventually you are going to come across something that turns out to be an alien lifeform. I swear you come across the coolest,weirdest stuff.

If it was a little more colorful, it would like a creature from a Dr. Suess book.

Wow. Get a degree in biology or something so if there is a new species you can recognize and claim it as your own. With something like that appearing who knows, like said earlier, what would appear!!

My apologies on bringing up an old topic....
But that image just rocks!!! One of the coolest single cell organisms ever!!!!
