Thanks, he did end up spitting the fish half eaten back out, so I fed the rest to my bigger sherman Nem. The Maxi do stay small less then 6" and never split unless you cut into them. They also don't walk around after the intial week or so. They are however a nem so they are very sticky to the touch. Overall the pro's outway the cons and they are one of my favorite creatures in my tank. I have 3 of them all side by side touching each other.
