I just found all 3 of my adult galacs dead in their tank! They all still looked perfectly healthy, in fact they look like they were just sitting around. One was a 6 or 7 year old male and the other two were his babies, not even a year old. Does anyone have any idea what could cause this? I am definately destroying that tank....thank goodness it is one that's not near the others. The only difference in that tank from all my others is that it was upstairs in the living room for a long time, but I recently moved it in the basement with the rest of the frogs.
