What is the Shrimp Fry Growth Tracker?
The Shrimp Fry Growth Tracker logs growth rate and size milestones for aquarium shrimp fry. Weight is one of the earliest and easiest signals of a health problem, both gradual weight gain and unexpected weight loss are worth catching early.
Aquarium shrimp generally live 1-2 years when they are well looked after. They are an omnivore, so their nutritional needs shift with age, size and activity. Aquarium shrimp are acutely sensitive to copper and to sudden parameter swings, and need a fully cycled planted tank. They are small enough to be eaten by most fish, so a species-only tank usually works best. Health problems that show up most often in aquarium shrimp include copper poisoning, failed molts from calcium imbalance, ammonia sensitivity, which is part of why tracking this over time pays off.

How does the Shrimp Fry Growth Tracker work?
The healthy range is drawn from breed or size-variant references for aquarium shrimp, adjusted for age where growth is still underway. Individual aquarium shrimp vary more than averages suggest, so read the number as a reference point rather than a measurement.
What affects the result
- Breed or size variant: which sets a very different healthy range than a flat species-wide number would
- Age: growing juveniles are compared against a growth curve rather than an adult target
- Body condition: since two animals at the same weight can have very different amounts of muscle versus fat
- Spay/neuter status and activity level, both of which shift metabolic needs
How do you use the Shrimp Fry Growth Tracker?
- Enter the current weight in whichever unit you use (lb, oz, kg)
- Pick your build for the species (Small or fine-boned, Average, Large or heavy-boned)
- Pick your life stage (Growing, Adult, Senior)
- Enter the age
- Press Calculate, then read the result alongside the sources listed below
If two people care for your shrimp, agree on one method and stick to it. Half of all confusing results come from measuring differently each time.

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for aquarium shrimp, but your shrimp may sit well outside it for perfectly ordinary reasons. Use the result to spot changes over time in your own animal rather than to compare it against other people's pets.
