Hi all. Our blue hippo tang suddenly died and I’m suspecting it was my fault We had a freeze last night and the tank temperature had dropped significantly lower (72 degrees) compared to the 82 we like to keep it at. I put in two smaller heaters equivalent to one larger heater (I’m in the process of buying a duplicate heater to put on the opposite side of the tank to regulate the temperature). Anyways, when I checked the temp of the tank this morning it was 87!!!!!!!!!! I nearly had a heart attack. I saw the tang was wedged tightly in a rock. I went to move her (him) and I couldn’t get her (him?) out. When I went to check on her, I tried to get her (him?) out of the rock again and it took a lot (I mean A LOT) of wiggling her back and forth… she floated to the top and was dead. I’m devastated. I don’t know if the temperature was the issue or something else. Please see attached photo. All the other fish seem to be doing fine (clowns, damsel, blenny, wrasse).
