Colony Passport
A tank card says what a colony looks like today. A passport says where it came from, and who has kept it since. Free, and it works for shrimp from any seller or breeder.
This records what you say, and shows the basis for each part. It is not an identification, a pedigree, a health certificate or a promise about what the offspring will look like. Nobody in this hobby can give you those from a form, and a record that pretended to would be worth less than nothing.
What it does give you: one permanent address for a colony's history, that you can hand to whoever you pass shrimp on to.
How much this proves
Every passport starts at self declared. The keeper entered this themselves. Nobody else has checked any of it. This is a record of what someone says, not a verification of species, ancestry, grade or health.
A passport only ever shows the level its record has actually earned. Levels backed by checks from other people, such as peer review, are only shown on a record once those checks exist and that record has passed them. A badge nobody earned would be a badge for nothing.
Already have a tank card? Tank cards describe a colony today. A passport records where it came from. They are different records and you can have both.
