No idea what this could be

Any idea what this could be? Iv tried researching it and it’s just odd. It does not look like anything Iv been coming across.

It would appear to be either a tunicate or sponge. I am unable to make out any real features other than the siphons to say reliably which it is. Can't say if it will be a problem either since I don't know the details of your tank. Some sponge and tunicate species are considered pests and will grow out of control. That isn't typically a problem in new aquaria, but it could be if you have a fairly mature tank and this stuff just recently started growing.

The tank is brand new. It’s only been cycling for 4 days.

Looks like skeletal remains of an old coral on dry rock...was your rock lr??

 

[BellaCoop]

Yeah it was LR. Should I be concerned at all? Iv never seen anything like it

The apparent two siphon tubes would suggest it is a tunicate.

You'll have to determine if this is so....picture is too blue....is it soft or hard?

Tunicate or a sponge is my guess. We have some sponge in the reef tank that has siphon tubes on them.

I agree with above posts. It's either a tunicate or a sponge. I would post a picture with white light so we can see more detail.

Sponge or tunicate.

Since your tank is brand new, there is a small chance it will survive. Too often these types of animals starve in our tanks due to the lack of free floating organic particles. There is also the issue of the nitrogen cycle development in your tank, the ammonia may kill it. I wouldn't be worried if it lives, though. A lot of people enjoy having this type of life in their tank. The microfauna in a reef tank is some of the most enjoyable stuff to observe.

I am pretty sure it is hard. When I get home today. I will get a picture with my White Light on it. Thank you for all the advice.

With it having the same pitting on it as the rock I still think it's dead calcified remains....
