hello, im quite new to tropical aquarium fish ownership and currently own quite a large biube aquarium not sure on the capacity but it is about two feet tall and about 18 inches in diameter so it is quite large. I currently have 5 white cloud minnows, 5 zerba danios, 9 neon tetras and 3 platinum blue guppys as well as a few fake plants a volcano to cover my filter/pump and a small cave. Im looking to add one or possibly 2 more colourful slightly larger fish to the tank and lookin round the internet bettas seem to fit the bill however I am aware there are a few problems i was wondering if 1 male/female betta would be suitable for my current tank if not could anyone suggest alternatives...budget isnt really an issue but nothin to expensive i am also lookin for fish which are relatively easy to care for both because of lack of time and experience.
