Stocking notes

Active barbs that need swimming length and a substantial group.

For planning, StockingLab models Odessa Barb at its approximate adult size rather than the juvenile size commonly seen in shops. That matters because space use and waste production can change dramatically as fish mature.

What the calculator checks

  • Whether the tank's usable volume is below the 80 L / 21.1 US gal reference minimum.
  • Whether the selected group is below the planner's typical 8 fish social starting point.
  • Whether target temperature and pH sit inside the planning range.
  • Whether prospective tankmates create predation, fin-nipping, territorial or water-overlap conflicts.
  • Whether too many fish accumulate in the same mid swim zone.

Before buying

Use this profile as a shortlist tool, not as a substitute for a dedicated care source. Confirm adult size, diet, sex ratio, habitat structure and locally relevant water conditions before purchase.
