Rainbow not eating right

[Valvaren]

I would absolutely not get another heat pad,your temps are fine i keep my brbs at no hotter then 82, 85 is very very extreme as far as temperatures for them and bordering on dangerous. I would check the rest of your husbandry and attempt different ways of offering food. We have two very experienced brb breeders on here and i highly reccomend waiting on their input.
