What is the maximum standard length (SL) typically achieved by the X-Ray Tetra in aquarium settings?
Answer
Approximately 4.0 cm or 1.5 inches
The X-Ray Tetra is considered a diminutive species, with most observations indicating that it reaches a maximum standard length (SL) of approximately 4.0 centimeters, which translates closely to about 1.5 inches. This small stature is typical among many members of the tetra family and makes them suitable inhabitants for smaller display tanks, provided their social and environmental requirements are maintained. This compact size is an important consideration for stocking density and tank layout, as they do not pose the long-term space concerns associated with some of the larger characins that might experience rapid growth in captivity.
