Many inhabitants of our reservoirs are very spectacular and people would love to keep them in home aquariums. But this happens very rarely, why?
This is often not possible for a number of reasons. First of all – the impossibility to create certain conditions. This is the temperature of the water, its composition, inhabitants, and so on. Also, there may be too little room for fish to live in aquariums. This is the same as putting a jaguar in a small aviary. He will not be able to live that long, since he needs space. Another reason is the specificity of fish food. Fish can feed on algae, some crustaceans, other fish and it is often impossible to find suitable food. Another reason is the inability to combine certain species in one aquarium.
