Species Overview

Common Carp

The common carp is one of the most widely introduced freshwater fish globally. Originally domesticated in East Asia over 2,000 years ago, it is a sacred fish in many cultures and the primary target species in European coarse fishing.

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.
