There are a few of these growing in my fuge. I have noticed some smaller ones on rock in the tank and have one in my filter now too. Anyone know what they are?

Hard to tell with the pic.. perhaps a sea squirt? Is there an opening on the top of them, and are they kind of jellyish?

They do appear jellyish possibly. Look more like a coccoon though I would say. They do have what i would say are like filter feeding fingers on the top. Here is a pic of the one in the filter.

The next question would then be are they bad , or will they cause a problem?

That looks almost exactly the same. Thanks for the replies everyone. I was just there looking at pictures and didn't even go into the sponges...
