Setup Guide for Beginners

Getting started is straightforward – follow these steps:

1. Rinse Thoroughly: Clean the tank with warm water (no soap) and let dry.

2. Add Substrate: Layer 1-2 cm of gravel or sand for plants and hiding spots.

3. Fill Slowly: Pour water over a plate to avoid disturbing the substrate; aim for 18-22 cm depth.

4. Cycle the Tank: Run a filter for 2-4 weeks with beneficial bacteria starter to establish the nitrogen cycle (essential for healthy fish).

5. Equip Essentials: Use a 10-25W heater (maintain 24-28°C), sponge filter, and low-output LED light (6-8 hours/day).

6. Stock Gradually: Start with hardy plants (Java moss, Anubias), then invertebrates like snails or shrimp, followed by 1-2 small fish.

Pro Tip: Test water weekly for pH (6.5-7.5), ammonia (0 ppm), nitrites (0 ppm), and nitrates (<20 ppm) using a liquid test kit.

Compatibility and Maintenance

Suitable for tropical freshwater setups only (not marine or coldwater). Recommended livestock:

• 1 Betta splendens

Weekly 20-30% water changes keep it pristine. Avoid overfeeding to prevent algae.
