What sets it apart

Set targets per tank

Readings flag against your numbers. Zero nitrite never shows as a warning.

Count a school as one

Forty tetras, one record, counted or estimated. Grade, merge, split one out.

Track spawns and brooding

Log mouthbrooders with a day count. Raise the fry as a school.
