It seems strange you are losing fish when they are obviously breeding? I would try a high protein diet using microworm and baby brine shrimp. These fish have tiny mouths and a lot of what i fed at first was simply to big. Freshly hatched brineshrimp 3-4 times a day will work wonders for putting a lot of weight on your fish.
Try a lower temp, i did some research on the weather in Myanmar and where the fish were found averages 70f…. This obviously means it gets higher but also drops lower than 70f.
I think a general temperature of 70f for maintainence and raising it to 80-85f for breeding should be a good starting point…
