I have been a fish keeper for a year now. I have a 15 gallon and a 5 gallon tank. I do at least a 50% water change weekly. I have a female betta, 5 glo danios, 4 loaches and a mystery snail in the big tank and until today a male betta and snail in the 5 gallon tank. I have live plants in both tanks. This past weekend I raked the sand and rearranged the tank. Tested the water 1 hr later and 24hrs later. No issues. Today I had a dead betta. I tested the water and had high ammonia. But is it due to the dead fish? The sand being mixed up? Advice is welcome.

What are you considering high ammonia?
Stirring up the substrate and a decomposing fish could both cause an ammonia spike.
I would opt for the dead fish being the cause as you didn't detect ammonia 24 hours after your substrate got disturbed but you did after the fish died.
