Hey everyone I'm new here, have yet to edit intro and profile yet. I have some questions concerning my JD. I am planning to switch substrate in my 75gal from gravel to sand. At the same time I am moving the tank to a different room so everything has to come out. My concern is my JH though. The fish has been acting very afraid lately and I'm not sure why. Anytime it sees people it freaks out and hides. This started a few weeks ago and I've had this fish over a year. I want to know what your opinion is on the best way to do the transfer for this fish. I don't want to stress it.
