newts constantly fighting and not eating

[munsterrr]

as the title says they have their own little "hide" spots but sometimes they fight. but they never eat(from what i see) ive tried "newt bites" "blood worms" and some other things and they dont eat it.

anyone got any ideas?

How big is the setup? What species are they? What are your temperatures? Got a pic of the enclosure?
