i think they are already stressed and shocked as my massive clown loach has already died and they are all at the top
is there any thing i can do to help with the stress
Add some stress coat after you do a water change and put cooler water in. And unplug the heater and once the temp starts to get lower than 74 degrees plug it in until it heats back to 78 then unplug it once it gets to 80 and unplug and repeat process until you can get a new heater.
Do a water change and add some ice cubes,keep the tank light out, also alot of aeration as high temp reduce the 02 in the water, do you have any extra airstones, also maybe put a fan near the tank with the lid off to cool the tank down.
yes i did the tank i moved them to was slightly lower in temp and i know the heater works in this one and i will keep on slightly lowering it through the night
Aspirin as a headache tablet that we use, just let them settle down now in peace and quiet, with no tank light on, but just keep checking on them, good luck hope they pull through there ordeal.
