Act as an experienced freshwater aquarium keeper. I want to set up my first tank under these conditions: volume gallons or liters, budget amount, available space dimensions and room, maintenance time hours per week, and fish I am interested in species. Follow these steps: 1) List the required equipment with price ranges, separating essential from optional (filter, heater, lighting, substrate, thermometer and water test kit). 2) Build a week-by-week cycling schedule, explaining the nitrogen cycle and which parameters to measure at each stage (ammonia, nitrite, nitrate and pH). 3) Tell me which week I can add the first fish and in what order, respecting the tank's bioload. 4) Assess whether the species I listed are compatible with each other, with the tank volume and with my local water hardness. If they are not, suggest alternatives. 5) Build a maintenance routine with daily, weekly and monthly tasks, including the percentage for partial water changes. 6) List the five most common beginner mistakes and how to avoid each one. Present steps 1 and 5 as tables. Base your recommendations on established fishkeeping practice and flag whenever a parameter requires an actual water test before any decision.
