yeah, the first is def a tourch, not a frogspawn
for the second one, what do you mean they go right back in the skeleton? do they actualy completly disapear into it? or do they just retract the tenticles towards the mouth?
whatever it is, make sure to feed it lots. unless i am completly wrong and no where near what it is for an ID, it looks like there is a lot of recession because there is no flesh on the skeleton, but jsut the polyps.
