First month with shrimp: checks and a simple log

After stocking, check animals and equipment daily, record feeding and maintenance and test more when something changes. The aim is to spot deviations early. Rearranging the tank every day makes causes harder to follow. Adapt this starting plan to your aquarium.

Look every day

Do visible animals walk and graze as usual? Assess fan shrimp by their own feeding behaviour too.
Are there animals losing balance, injuries, visible dead animals or several shrimp gathering at the surface?
Are filtration and any heating or cooling working? Check temperature and water level.
Are there leftovers, substantial decaying material or sudden cloudiness?
Have new animals, products, plants or maintenance coincided with a change?

Calm grazing is a useful observation, not a health certificate. Hiding after a move can occur, but it does not establish a fixed period in which loss of balance or deaths are normal. Avoid dismantling the tank to count every animal.

Testing and maintenance

Set a weekly time to review your readings and maintenance log. In a new, uncertain or disturbed setup, test more often as needed. Check ammonia and nitrite with abnormal behaviour, deaths or uncertainty about filter function. Use nitrate and other appropriate measurements to assess trends. GH, KH, pH and conductivity also matter for Neocaridina when water source, substrate or minerals change.

Record replacement-water volume, preparation, temperature and key readings. Use the water-change routine and feeding approach. Recheck equipment after maintenance. A zero reading in unloaded new water does not prove an established biofilter.

Responding to an alarm sign

With several animals in distress or dying, stop any ongoing suspicious addition, check water and equipment, remove dead animals and leftovers and provide appropriate gas exchange. Reduce detected or likely exposure using suitable clean water where needed. Do not wait for the scheduled testing day. Avoid stacking salt, medicines, pH products and minerals on suspicion alone. Follow the problem route in the water guide.

Prevent recurring mistakes

Buy animals only when the tank and water system suit the chosen species.
Assess uptake and leftovers before increasing food.
Treat chlorine or chloramine if present; conditioner does not establish that any tap water is suitable.
During routine maintenance, avoid changing substrate, all filter media and the water recipe together.
Choose a tank without fish if you want to exclude fish predation on juveniles.
Do not chase rapid colour changes or a promised number of weeks until the first young.

A reusable log entry

After the first month, assess whether the routine is repeatable and unexplained changes have been resolved. If losses persist, investigate readings and conditions further. Do not automatically buy more shrimp to replace them.

Sources and scope

Grazing behaviour and water chemistry are supported by the cited sources. The checking frequency and log are our practical planning. Observed behaviour does not establish a diagnosis, and a month without juveniles does not prove failure.
