Got a question about thistles?

[Jessie]

I am getting 2 adults could i keep them at a 75 heater? since there fully grown.

That should be fine

i would be careful about humidity at those temps

these like it hot and dry, so if the temp is in the mid 70s rather than mid 80s, be sure the air is pretty darn dry
