I would like to have just about every type of fish going, but limited by what's peaceful and practical and by space etc. so how many species have you got?
My book says 15,000-20,000 freshwater only fish in the world and about 1,500 are suitable for aquariums. And I don't know about saltwater(I don't think anyone really knows).Dino said:If I am remembering correctly, there are over 5800 described species of freshwater fish.
Less than 10% of that is easily available to the hobbyist.
