Someone posted a similar thread last week, but about dwarf frogs. I'm not sure if it's the same for ACF. What is the highest temperature that they can tolerate? I've just been away for a couple of days and returned to find that all of my ACF tanks are at 30 to 32 degrees C (86+ F, I think). I'm trying to gradually lower the temperature with colder water. Should I be doing this gradually? I don't want to shock them with such a sudden change in temperature, but I don't want the high temperatures to affect their health either. I'm aiming to lower the temperature by about 4 or 5 degrees tonight and I'll aim for the same tomorrow. It's been unusually hot this week but I live in England so I'm expecting this to be a very short-term problem.
