Tips for Caring for Mid-Level Schooling Fish

To ensure your mid-level schooling fish thrive, provide them with the right environment. Here are some tips to help you care for your mid-level schooling fish:
Tank Size
Ensure your tank is appropriately sized for your mid-level schooling fish. Most fish on our list can be housed in a 15-gallon tank, but it’s crucial to research the specific requirements of each species before adding them to your tank.
Substrate
Consider using the Fluval Stratum substrate in your aquarium setup. This substrate offers a natural appearance and promotes healthy plant growth. Many mid-level schooling fish prefer planted tanks, and Fluval Stratum can help you create a thriving and visually appealing aquatic environment.
Filtration
A standard aquarium filter typically works well for most mid-level schooling fish. However, ensure your filter suits your tank size and fish population. For instance, betta fish may need a gentler filter as they prefer calm waters. However, betta fish need a filter to maintain water quality and eliminate harmful toxins.
Feeding
Investigate the specific dietary requirements of each fish species in your aquarium. For example, many mid-level schooling fish, such as guppies and bettas, are omnivores and need a diverse diet containing meaty and plant-based foods.
Tank Mates
Research each species’ compatibility when selecting tank mates for your mid-level schooling fish. For example, dwarf gouramis get along well with other peaceful fish like rasboras and tetras but may become aggressive with other gouramis. Likewise, Angelfish can also display aggression and might need a larger tank to coexist peacefully with other fish.
Water Quality
Monitor your aquarium’s water quality closely. Test the water regularly and perform routine water changes to maintain a healthy environment for your fish. For example, seeing your fish swimming sideways or exhibiting other signs of distress may indicate poor water quality.

Mid-level schooling fish make a fantastic addition to any aquarium, providing color, movement, and a fascinating new aspect to your aquatic habitat.
