Swollen Euphyillia

[Timbits]

i noticed my hammer, frogspawn, and torch coral looks different than usual. The best way i can explain it is, that it looks swollen. it still opens up but just looks really wierd! Definately not the same as when i first got it. These are just frags btw, i seem to see something happening to a couple of my zoas as well, they open but not all the way. ph, alk, ammonia, nitrite, nitrate, cal, all in check.

Does anyone know what i'm talking about or why it might be doing this? is there something wrong with it or am i tripping out lol

thanks
