My green brain's flesh has been coming up its skeleton from the base, im not sure if it started after doing a long over due water change or if it started earlier. What's going to happen to it now??? Ive tried to get the water levels to its stated requirements and im not sure if its doing better. It is quite expanded during the day on the top, but i see lots of skeleton underneath and its tenticals do not come out as they used to.. advise please......Tony
