Been doing abit of Aqua re-scaping today. Under one of my LR I found these red thingies, in the water they were shaped like the ends of bubble tip anenomes.

The LR was living on substrate and this would have been growing in the sand.

Any ideas ?

Looks like sponge, what does it feel like?

Hi Warr - I second Kanga's suggestion - definitely think that those are sponges. They are good for a tank as they help in "natural filtration".

There are many little critters that start to grow from live rock, which assist in natural filtration, ie: fan worms, sponges, tunicates, etc....

Weird that it's growing in the substrate. I would think the sponge would need good water flow.
