heckelii are late maturing to breed. IMO, no way they'd show breeding behavior at under 3 1/2 inches.
they probably need more space.
They were going to go into the 70 at 4 inches, they were pretty close to eing able to, only in the 30 for about a month. They were cuddling up next to each other and digging a hole in the corner, idk about the breeding habits thats what was going on
