What extremely fine sustenance is required for newly free-swimming X-Ray Tetra fry?
Answer
Infusoria or commercial fry powder
Once the X-Ray Tetra eggs hatch, the fry subsist on their yolk sacs for the first couple of days. However, once they become free-swimming, their mouths are extremely small, necessitating very fine initial sustenance. The primary food sources recommended at this delicate stage are infusoria or a specialized commercial fry powder. Only after they can consume these fine particles can they graduate to slightly larger options like microworms or newly hatched brine shrimp nauplii.
