Aquarium Setup for Oranda Calico

 

Aquarium Filtration

Oranda Calicos are sensitive to water quality, so an efficient filtration system is crucial. Use a canister filter or a high-capacity hang-on-back filter to ensure proper water movement and filtration. This helps maintain clear water and prevents the buildup of harmful toxins like ammonia and nitrites.
