Hi,i have recently bought a blueplanet 20L aquarium from wellington. I havent kept tropicals before but have kept goldfish on and off for about 6 years. anyway i was hoping someone could give me a few tips on setting up the tank and maintenance etc. i would also like some recommendations on what fish and how many fish i can keep in here. some fish i had in mind were a siamese fighter, honey gourami, bristlenose, black widow tetras and rainbows. i dont know wether these will be compatible or suitable for my tank so any help would be appreciated. thanks matt
