My 2.5 inch Brazilian horned frog has not eaten in 5 days losing some weight. At what point does a person need to try and force feed frog? I don't want to shouldn't have to but not sure how long I should wait to try?

When I bought the frog I don't think he liked setup had him in 10 gallon aquarium then moved him to a medium critter keeper. He may have gotten stressed out but not sure .

Should I keep temps around 80 ? I am worried that if keeping him at these temps it will only speed up metabolism and he will lose weight even faster.
