I bought a 10 gallon aquarium for my son back in April. Long story short. Went through over a dozen fresh water fish. We couldn't keep them alive. The last one (catfish) went belly up a month ago and they are pretty hearty! My son lost interest which I can't blame him. Went through the whole issue with 'ick'. Everyone I talk to goes through the same disappointment with aquariums. A co-worker told me last week that he lost all his tropical fish and coral in his 70 gallon salt water aquarium.
Spend your cash on home entertainment products not fish.
