So I added 3 blue legged hermits to my tank two days ago. They have been in the same spot for the last two days. They are alive I know that but they are not moving around my tank.My sg
is at .26 and my water is great. My temp was sitting at 75 ( it was one of those pre set heaters u can't adjust) so I went out and bought a marineland adjustable heater and slowly raied the temp tp 79. Am I doing something wrong to cause them not to be active?
