Your first freshwater aquarium: planning a confident start
A successful aquarium starts before the first fish arrives. Plan the layout, water checks and a properly matured filter.

It is tempting to bring everything home from the shop at once. Treat the first visit as preparation instead. Decide what you want to keep, how much space it requires and how you will check that the aquarium is ready. A simple aquarium journal helps you keep track.
1. Write a wish list
Record the space available, animals that interest you and time you can give to maintenance. Sketch the aquarium, stand and storage for buckets and equipment. Take the plan to a specialist shop. Ask about the animals' adult needs, not only whether the fish on sale would fit today.
Use a suitable load-bearing support, avoid direct sunlight and leave access for maintenance. The tank must accommodate adult animals and their swimming needs. Read LICG’s setup guidance (Dutch) and your aquarium manufacturer's placement instructions before filling it.
2. Plan the layout around the equipment
Mark the filter position and leave room to open it later. Record model numbers and keep manuals together. List the substrate and plants you choose so that you can ask specific questions if something goes wrong. Photograph the empty and planted tank for your journal.
3. Mature the filter without fish
A new aquarium is not biologically ready. Cycling grows bacteria that process ammonia and nitrite. Choose a fishless method with an appropriate aquarium ammonia source, following a reliable protocol and product instructions; do not use household cleaning products. Test ammonia/ammonium and nitrite. Clear water or a fixed number of weeks does not prove readiness. OATA explains filter maturation.
4. Make decisions from measurements
Keep a table of dates, temperature, test results and anything added to the water. Check what your test kit actually measures: a general strip does not automatically replace every necessary test. Ask for help interpreting results if needed. Add animals only once the cycling protocol is complete and water conditions suit the species.
- Have you recorded the exact species' care requirements?
- Are the necessary tests available and within date?
- Are filtration and temperature control working as intended?
- Have you planned gradual stocking and follow-up checks?
Avoid scheduling the first arrivals for a busy day. Time to observe them calmly is worth as much as another accessory.
This guide is a starting point for freshwater aquariums. Check the exact species’ care requirements before buying animals and follow your equipment manuals.
