Beginner guide: prepare and maintain your first shrimp tank

Choose the animals and the water you can prepare reliably first. Then furnish the tank, assess filtration and grazing space, and only afterward buy shrimp. This guide helps decide the next step. A fixed startup interval or one satisfactory reading cannot establish that a tank is ready.

Choose a manageable water system

Neocaridina davidi is often a practical option for a first colourful freshwater colony. Amano has a different reproductive strategy: do not expect a self-replenishing colony in an ordinary freshwater tank. Bee/Taiwan Bee and Sulawesi Cardinal call for different water choices. Caridina includes different species and is not one shared care recipe.

Measure source water and ask about the seller’s conditions. Suitable tap water may be enough; buy RO and minerals for a defined water plan. Use the water decision guide for tap water, RO, remineralisation and water changes.

Build around care and maintenance

Choose space, support, temperature management and equipment for the intended animals. LICG prefers at least 30 litres for a first shrimp tank; this is housing guidance, not a carrying-capacity guarantee. Protect filter intakes and retain access for inspection and maintenance. Avoid an unintended conflict between substrate, rocks and water.

Assess readiness through function

A new aquarium can be clear without functioning adequately biologically. The filter must process the load and useful grazing surfaces must develop. Establish this without shrimp. Follow measurements using an appropriate test range and assess their course, not just the number of weeks. Visible biofilm is supplementary and cannot replace water checks.

Check	Insufficient evidence	What to assess
Filtration	One zero reading in freshly filled water	Processing of the controlled load and the measurement trend.
Water preparation	TDS matching an online table	Suitable composition, temperature and reproducible preparation.
Food and layout	Lots of new moss or a white coating on wood	Established accessible surfaces and an appropriate feeding plan.
Equipment	Everything is connected	Actual filtration, protected intakes and measured temperature.

Purchase and transfer with known conditions

Ask about species, water, age and recent losses. Bright colour or active behaviour does not establish absence of disease. Prepare suitable receiving water beforehand. Gradual acclimation may help, but longer dripping is not automatically better with polluted transport water. Substantially incompatible water systems cannot be reconciled simply by waiting longer.

Observe and maintain from the first day

Follow behaviour, food intake, filtration and temperature. Choose portions from uptake and leftovers; one daily or weekly dose cannot fit every colony. Base water changes on load and the situation, using water prepared outside the tank. Evaporation top-ups serve a different purpose: evaporation leaves minerals behind. Record changes and avoid removing all grazing surfaces at once.

Problems change the priority

Loss of balance, several dead animals or a group gathering at the surface warrants immediate checking of water, filtration and gas exchange. Include recent additions and maintenance. Do not diagnose disease from one sign or add treatments at random. Follow the water guide’s problem route and seek informed help with readings and photographs for persistent or severe problems.

Not seeing young is a different question from acute losses. First establish the species’ reproductive strategy and what you actually observed. Animal health takes priority over colour and breeding results.
