Setting up a shrimp aquarium: decisions and checks

A suitable shrimp aquarium combines appropriate water, functioning filtration, accessible food and refuges, and manageable maintenance. Start with the actual animals and your water source. Then assess what substrate, equipment and layout contribute before purchasing shrimp.

Choose the decision you need to make

Question	Work through	Check before proceeding
Which animals fit my circumstances?	Species-based design and the water decision guide.	The actual species or line is known and suitable replacement water can be reproduced.
Which tank and equipment?	Tank size, location and equipment checklist.	Support, actual water volume, equipment and maintenance access fit the intended animals.
Which substrate and decoration?	Substrate comparison, wood and rocks, plant choice.	Origins and water effects have been assessed; refuges and useful surfaces remain accessible.
Which filter and current?	Filter comparison, intake protection and gas exchange.	The complete setup functions and protection does not block necessary flow.
When can animals enter?	Fishless cycling and the stocking checklist.	Repeatable nitrogen processing, suitable water and food provision have been assessed; one zero reading or calendar date is insufficient.

Use the installation sequence to turn decisions into practical steps. Record open questions and resolve the conditions depending on them before buying animals.

Substrate, water and species must fit together

An inert substrate is intended not to deliberately change water. An active soil may instead serve a chemical role in a planned Bee/Taiwan Bee system. A nutrient base under gravel is a different product again. Read the actual effects and startup instructions.

Amano and Cardinal are also Caridina; they do not automatically belong in a soft-water bee setup. The warm, alkaline Cardinal example does not apply to every Sulawesi species either. Fan shrimp require a food-bearing current in which they can filter. Abundant moss and sinking food alone do not automatically provide that function.

Example: a manageable Neocaridina setup

Assumptions: you choose Neocaridina davidi, measured source water fits the animals, you begin without fish and want manageable planting. LICG recommends preferably at least 30 litres for freshwater shrimp. This is housing guidance, not evidence that 30 litres supports every stocking level.

Choose an accessible aquarium and suitable support. Check measured temperature at its intended location.
Use materials that do not cause unwanted changes to the water plan. Retain an observable feeding area and refuge structure.
Assess a suitable sponge or other protected filter by function and maintenance. Foam still offers no absolute guarantee for every small animal.
Choose, for example, a manageable amount of moss, Anubias or Java fern with assessed origins. Keep filter and surface accessible.
Record water preparation and measurements during startup. Assess established grazing surfaces and plan supplementary feeding.
Check stocking conditions and follow animals, food uptake and water after introduction.

This example specifies no fixed animal count, food mass or waiting period. Reassess if an assumption changes, such as a different species, fish or unsuitable source water. CO2 injection is a separate decision with measurement and equipment requirements, not a mandatory stage.

Build in maintenance before adding animals

Try access to filter, plants and debris areas with the maintenance check. Prepare replacement water using a repeatable recipe. Preserve useful biological media and grazing surfaces during maintenance; clean appearance is not the same as functioning filtration.

For an occupied aquarium, use a separate rescaping plan or substrate-replacement plan. During acute deterioration, follow the problem route. Necessary first aid need not wait for the next maintenance day.
