i had two tigers in a 25 gallon tank that i just switched from terrestrial to 2/3 land 1/3 water. both of my tigers were doing great and i noticed no problems at all. then about two weeks after adjusting my tank the older tiger stopped moving and i discovered him totally dead, a day later.
my best guess is either bacteria introduced from the transitional tank i used. or too much stess from the move. he was really healthy up untill a day before his death, and theres no visible signs of disease or anything. he didnt bloat or anything. so im really hoping that someone could help me understand why my pet is dead.
