They are not the same. One of the reasons it's called a confusa... you guessed it, it's kindof hard to ID. A confusa has a couple of different growth characteristics, and depending on where it was fragged, and where it grew, it can look different. A confusa CAN look like a spongodes, but it can also look like a digi, or even look like a capricornis if it's fragged just right (until it grows out, that is). I personally believe that you have a spongodes, but it's the size of the polyps that makes it easier for me to tell. Without a reference in that pic, I just don't know. My spongodes has the biggest polyps by far of any monti I've ever seen. It's yellow base with dark tan polyps. It's my favorite colony. I've broken it 4 times by accident, and I've always superglued it right back where it was.
