Unfortunately, 35l won't be big enough for long. Don't feel bad, it seems only logical that pet stores would give good advice, but fact it, they often don't, and it's something that most people on this forum have been bitten by. They might be ill informed or out of date, they might be a part time kid in high school student whose only real knowledge comes from a 2 hour training seminar, or they might just be after a sale, facts be damned. It's the customer and the fish that suffer for it, but you're in a good place in that respect.
Blood parrots can reach up to 10 inches (at this size, the 1" per gallon rule goes out the window). I don't know much about them in particular, posting in the hybrid fish section would be a good idea, but a tank 2-3 times that size would probably be minimal for one.
On the topic, how did you handle tank setup/cycling? That's another subject fish stores nab people on a lot - reviewing the threads on cycling in the new to the hobby section would be a good idea (Easy way: Find a post by Miss Wiggle and check out the links in her sig - 90% of what you need to know about fish is in those links)
