my neon tetra is hiding in a cave that none of my other fish have gone near does this mean shes pregnant and hiding to lay her young
No. Neons are egg scatterers. They have a very specific egg laying pattern, which occurs in the morning, and requires nearly perfect conditions. In any case, a female ready to lay eggs is only slightly larger and acts like any other tetra.
It's possible that the tetra is sick or stressed out. Fish commonly hide when they are stressed or sick.
SHELONELELY!
Im not sure
