It moved onto the hob filter I have on the drop down tube and tried to go into the tube through the slits. The cover thats on it has vertical slits on it. All but about 3 or 4 tentacles are gone. It was 2.5 inches in dia. I had to cut the slit thing off of it. Now it looks like the shape of a pizza with 1 or 2 slices cut out. Will it grow back? I put it in a hob container and put it close to the 36 watt pc, bout 3 inches, to get more light if it needs it to regenerate. I dunno if it will live or if it will die and I would like your opinions or if you have heard of it coming back after something like this.
