So yesterday I decided that I should try another fish after the loss of my first fish. I went and got me a nice looking fire goby, brought him home, did the usual stuff to get him in his new home ie floating the bag in my tank for over an hour, adding 5ml of my water to bag every 20mins after the first half hour he was there. I let him out and he was swimming happily around the tank. I tested the bag water for PH and salinity and was same as tank. I woke up this morning to a dead goby
what am I doing wrong here! I'm really bummed about all this. My tank parameters are fine, Ammonia 0 nitrite 0 nitrate 5. PH 8.2 salinity 1.025 temp 23c to 24c. Is there anything else I can test for, check or change?
