If you’re dreaming of all the beautiful marine fish you’d love to own, then it’s time to know the saltwater aquarium cost. Normally, saltwater fish are hard to maintain than freshwater ones, because of the rigours of setting up and maintaining the saltwater aquariums. Besides, the types of aquariums play a vital role in determining their cost. For instance, a small reef fish tank of 60-80L capacity might cost you anywhere between 2000-3000Dhs to maintain. However, this price goes up to around 35000Dhs if you want to have a large specialist tank of 500-1000L capacity. This is just for the maintenance of the tank. So you could definitely imagine the cost of their supplies.
