The setup is a 58 gallon with a 20 gallon refugium and 20 gallon sump.
No corals, just fish, hermits, snails, LR
and then macro in the fuge.
Last week the AC
unit in the room with the fish tank overheated and quit working while I was at work (window units). The door was closed to that room at it reached over 100 degrees outside that day (and in that room). The tank temp was over 86 degrees, that's as high as my thermometer went.
I got another AC
unit in there from another room, took all the lids off the tank, and turned off lights in an effort to reasonably quickly bring the temp down without doing it too fast. (maybe that was a mistake cooling it down too slowly instead of adding some cold RODI
water or ice?)
The sand sifting starfish I had was dead the next morning.
I have a coral beauty, 2 clowns, and 1 yellow watchman goby. The snails and hermits all seem just fine. The clowns and goby are fine.
The CB has been hiding much more and wasn't eating. There's lots of rockwork and I couldn't get a good look at her until 2 days ago. Her color is very pale and she has some white spots on her. She did eat though last night for the first time in a week.
I haven't added anything at all to the tank since March and the high water temps is the only thing different that has happened.
temp is stable at 78-79
I can't get a picture because she stays hidden but her color is very pale and she has white spots on her fins, head, and body....not a lot, but they are noticeable.
Is this ick and can it be caused/triggered by over stressing the fish with the high temps or is this something else?
The tank itself has been up and running, fully cycled since January. I do use a skimmer too and weekly water changes with RODI
Should I move to a hospital tank and....?
The clowns leave her alone and the goby spends his days in the rockwork so she isn't getting picked on.
thanks in advance
