Hello, so apprtenly for 5-6 hours my tank’s heater was left unplugged 2 days ago and it dropped significantly from 78-76 degrees to 68-69 degrees. , after that when the tank temp had dropped my molly fish’s back got hunched, will it get better? Does my fish have permanent damage from that temperature drop?! The temperature is better now however (78)i plugged it back in. . and as so far goes for the parameters i am still fixing the pH.
