Are these safe or not. Thanks for looking.

Wow, no one saw these before?

Looks like sponge. Is it purple?

 

[rwells]

I wish it was but it can also moves but very slow like a snail.

Are you sure it isn't the movement of the water that makes it look like it moves?

 

[rwells]

Well it looks like it moves when I turn the coral upside down. Do you know of a site where I can look this up?

 

[Jan]

No, sorry. I was just looking. I have a sponge that grows in my DT that looks like this. I have about 5 different kinds of spong in my DT. I've id'd most. This is why I said sponge. It looks very similar to what you've posted.

I just saw something that looks like it while browsing and it seems like you're right. I will take another look at it and see if it really moves. Thank you.
