Saltwater aquariums, with fish only, are simpler than you may think. Water quality, fish compatabitly, filtration, lighting, and feeding are key factors to ensure a healthy life for the saltwater aquatic community. Saltwater fish are primarily caught in the wild and put into a contained enviroment. If not maintained properly, water quality can become dangerous, leading to bacteria infections, parasites, and death. Dedication, patience, and working together with a professional can greatly improve your aquariums balance and overall health of your aquatic community.
