Rainbow not eating right

[Gluttony]

What would I know? I have only had my 8 brbs for 7 yrs, but I have kept them at temps of 82-85 without issue, if you google their requirements those are the temps recomended....I dont think you need the extra heat mat, and I only suggested raising the hotter part of the enclosure to 84- 85 which is standard for brbs. Anything higher than that would be extreme and dangerous. Braining is splitting the head or just piercing it to expose brain fluid......Also with raising the temp comment I did not take into consideration the size of the enclosure....forget I said anything, since everyone else seems to know better on this site...good luck
