Guys,
If I buy fish from the sponsor here. What is the definition of the size?
From mouth to the base of the caudal fin or the tip of it?
Thanks.

The sponsor will tell you. But I believe all the sponsors measure from tip of mouth to tip of tail except for Lucky Tropical.

"Standard measurement" used to mean from mouth to base of tail. From mouth to tip of tail was called "total measurement". These days the measurement is most nearly always from mouth to tip.

Smart breeders and distributors give a half inch size range. I think that most purchasers are happy if they a good quality healthy fish that falls into the size range.
