What is the Angelfish Nitrogen Cycle Tracker?
The Angelfish Nitrogen Cycle Tracker tracks tank cycling progress through ammonia, nitrite and nitrate stages for new angelfish tanks. Water quality is the single biggest factor in aquatic animal health. Far more animals are lost to poor water parameters than to disease introduced from outside.
Expect roughly 8-10 years with an angelfish, which is worth factoring into any long-term plan. As an omnivore, what an angelfish needs from its diet changes across its life stages. Angelfish are tall-bodied cichlids needing a deep tank of at least 110 liters, not a standard shallow one. They become territorial as they pair off and will eat small tankmates such as neon tetras. The usual suspects for this species are hole-in-the-head disease, ich, fin rot, so any noticeable change is worth following up.

How does the Angelfish Nitrogen Cycle Tracker work?
The figures are based on commonly cited aquarist rules of thumb and safe parameter ranges for angelfish, scaled to your tank or livestock details. Use it to know roughly where you stand and what to ask about, not to rule anything in or out on its own.
What affects the result
- Tank size and current stocking level
- Filtration capacity: which affects how much waste the system can safely process
- Feeding habits: since overfeeding is a leading cause of poor water quality
- Source water quality before treatment, which varies by location
How do you use the Angelfish Nitrogen Cycle Tracker?
- Enter the current temperature in whichever unit you use (F, C)
- Answer "Where did you measure?"
- Pick your time of day (Daytime, Night-time)
- Press Calculate, then read the result alongside the sources listed below
Use this alongside your own observation, not instead of it. You notice changes in your angelfish that no calculator can pick up.

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