What is the Betta Fish Quarantine Timer Tool?
The Betta Fish Quarantine Timer Tool tracks recommended quarantine duration for new betta fish before adding to a display tank. Small, regular health checks and a consistent care schedule catch problems earlier than waiting for obvious symptoms to appear.
Betta fish generally live 3-5 years when they are well looked after. Diet-wise they are a carnivore, which shapes almost every feeding decision you make. Bettas need a heated, filtered, cycled tank of at least 19 liters with gentle flow. They breathe air from the surface, so the tank must never be sealed. Males cannot be housed together. The usual suspects for this species are fin rot from poor water quality, swim bladder disorder from overfeeding, ich, so any noticeable change is worth following up.

How does the Betta Fish Quarantine Timer Tool work?
Where a schedule is produced, it follows commonly recommended cadences for betta fish; where a score is produced, it uses a simple, transparent scale rather than a black-box formula. It is a starting point, not a verdict. Somebody who has actually examined your betta fish will always know more than a formula does.
What affects the result
- Age: younger and senior animals typically need more frequent checks than a stable adult
- Existing health conditions: which may call for a tighter schedule than the general default
- Lifestyle factors such as indoor/outdoor access, which affect exposure to parasites and injury
- Your veterinarian's specific recommendations, which should always take priority over a general default

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for betta fish, but your betta fish 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.
