It sounds like you've really put effort into maintaining your tank, and I know it can be frustrating when your fish don't seem as active. Here are a few things you might want to consider:
- Cyanobacteria: This could be impacting your fish’s comfort if it's affecting the water quality. Continue removing it and consider reducing light exposure to help control the outbreak.
- Water Parameters: Your parameters look generally okay, but keeping an eye on nitrate levels is important; higher nitrates can cause fish stress. Regular water changes should help manage this.
- Overdosing Conditioner: Using too much water conditioner can lead to chemical imbalances, so try to stick closer to the recommended doses.
- Tank Environment: With limited hiding spots, your fish might feel exposed, leading to less activity. Adding more plants or decorations could create a more secure environment.
- Tank Lighting and Stress: Too much light from the greenhouse/hydroponic system could be stressing the fish. Adjusting the light levels if possible might help.
- Algae: For green spot and brown algae, maintaining regular cleaning and watching nutrient input can help. Amano shrimp are usually great at controlling certain algae types, so consider expanding your cleanup crew if needed.
