hi unfortunately the temp spiked in the tank nd hit 40 and as could be expected there were a lot of casualties but we did manage to save some and although we couldn't move the tank to a cooler part as our house is too small by running fans on it and doing a water change every week as normal taking the lid off the tank no light and water bottles constantly swapping over we have managed to make it through with a few surviving fish and about 30 fry which I hope will be a little tougher from their experience. Sorry its taken so long to reply I have had a lot of issues getting on the site

. Do you think that the fry will be able to survive more readily after this? Oh and I also added some more air curtains and stones so the water had more oxygen going through it
