White Fluffy Balls? I.d Required

[1entra]

Hi there,

Whilst having a look around my tank yesterday I noticed 2 fluffy looking balls on 1 of my pieces of LR. 1 of these balls was on top of the rock and covered in brown algae/diatoms (as my tank is just finished cycling and I am looking to add some CUC in the next few days) and has a small hole in the centre of it like either a mouth or an enterance for something that could possibly be living inside it. The other ball is in a hole on the same piece of LR so I can not see if it also has a hole or not .

They are approx 1cm diameter and very fluffy looking like they are made of fur or something! I have just had another look to where I seen them and they are both still there and so have not moved.

I was just wondering if anybody else has seen these or similar in their tanks and was hoping somebody may be able to help ID them for me as I have never seen anything like them before. I know the description aint brill but thats really all there is to them and they in too awkward a position for me to get a picture!

Thanks

Thanks for the reply pengy666, but nope they look nothing like that at all . look more like round furry dice you can get for your car rear-view mirror. look really fluffy and furry.

The one not covered in brown algae and in the hole in the rock is a really pearly white colour! its atcually surprising how white and clean looking it is!!

Anybody else...?

There just sponges wouldn't worry about them. some times you'll get them in pink and yellow too.

Are you sure matthew as I was starting to get a bit worried about them! So they are ok to leave in the tank then yea?
