What microscopic food sources are required for newly hatched X-Ray Tetra fry?
Answer
Infusoria and Liquid fry food
Caring for newly hatched X-Ray Tetra fry necessitates a specialized, incredibly fine diet because they are too small to process standard food particles immediately after becoming free-swimming. The initial, crucial sustenance must consist of microscopic food sources. The primary recommendations for this earliest stage are Infusoria (naturally occurring microorganisms) or commercially prepared liquid fry food formulations. Only after the fry have noticeably increased in size and begun developing color can the diet safely transition to slightly larger items like freshly hatched brine shrimp or finely crushed flake food.
