Found a Sea Apple

Hold on there people, no need for finger pointing. This post was an effot to ID something that i tried very hard to ID on my own. I appreciate all efforts to help when I have a question, even if they aren't definative answers.

I did what I thought best based on:

1. I found this creature in the substrate of the 20 gallon tank that I had just combined with my 30 gallon the day before.....no more heater and barely 5 gallons of water. I didn't want to risk transfering the creature after it had been through such a serious change in water conditions.

2. As the title of this thread suggests, I thought (and still haven't ruled out) that this was some sort of sea apple or cucumber, in which case I was definetly going to remove it. Too much time and effort for a potential tank killer to wipe out everything.
