Species Overview
Cobia
The cobia is a powerful pelagic fish that often follows large rays, sharks, and turtles. Its flattened head and elongated body resemble a shark. Excellent table fare with firm, white flesh, it is increasingly farmed in aquaculture.
Oscar
The oscar is a large, intelligent cichlid native to the Amazon basin. Known for its dog-like personality, it can recognize its owner and may beg for food. Oscars rearrange their tank decor and require spacious aquariums with robust filtration.
