a few ?'s

Ok after I Lost 8 fish overnight to a starfish that I removed I replaced one of those fish. It was a lawnmower blenney that I replaced. The one I had was 6 and half inches long. well anyways the new one I have is about 3" long right now. When I bought it its belly was normal. not fat and not skinny. Well today I noticed that its stomach is huge. I almost thought it was pregnant. could this be a problem? I know its eating flake food but thats not all its eating. I dont have an algae problem so I dont really know what else it is eating cept maybe the hard green algae on the back glass(its also on front but I havent had time in last 2 weeks to clean the front glass). Any thoughts as to why this lawnmower blenny is really fat and if I should worry about it?

The next ? I have is has anyone seen a yellow Leather split? My yellow leather used to be round all the way around it. now the entire middle seems to be closing. It looks like a mushroom or ricordia splitting cept its bigger. if you look down at it the middle has a dark line going across where the trunk of the leather is "caving in". I think its splitting but not sure. all the yellow polyps are extending fully during the lights being on. The reason I think its splitting is because it looks like all the ricordia and mushrooms that I have had split.

The other ? is on frogspawn. is there such a thing as over extended polyps on frogspawn? It is amazing to watch my newly acquired frogspawn(actually ive had it a week) go from almost completly withdrawn to fully open. its a perty frogspawn.

Thanks for answer my ?'s =]. seems funny that I have had this tank up almost a year and a half and I still have ?'s.
