- Place the thermometer where you can see it without disturbing the fish.
Lighting Requirements
Lighting affects fish behavior and plant growth. Different fish require different light levels. Some need bright light, while others prefer dim light.
| Fish Type | Light Level | Light Duration |
| Freshwater Tropical | Moderate | 8-10 hours/day |
| Deep Water Species | Low | 6-8 hours/day |
| Marine Reef Fish | High | 10-12 hours/day |
Aeration And Circulation
Aeration adds oxygen to the water. Circulation moves water to keep it clean and healthy. Both are important for fish survival.
Use this checklist to set up aeration and circulation:
- Install an air pump with suitable air stones.
- Place water filters to create gentle water flow.
- Adjust flow strength to avoid stressing fish.
- Check equipment regularly for proper function.
Creating Ideal Habitats
Setting up an aquarium for fish with special needs requires care. The right environment helps fish stay healthy and happy.
Choosing proper elements like substrate, plants, and hiding spots makes a big difference. Each fish species may need unique habitat features.
Substrate Selection
Substrate is the material at the bottom of the tank. It affects water quality and fish comfort. Different fish prefer different types of substrate.
- Sand is soft and good for bottom dwellers like catfish.
- Gravel allows good water flow and suits many tropical fish.
- Soil substrates help plants grow well in planted tanks.
- Crushed coral raises pH and hardness, ideal for African cichlids.
Plants And Decorations
Live plants provide oxygen and shelter. Decorations add hiding places and reduce stress. Choose items safe for your fish species.
| Plant/Decoration | Benefit | Best For |
| Java Fern | Low light, easy care | Beginners, small fish |
| Amazon Sword | Large leaves for shelter | Mid to large fish |
