Angelfish in trigon 190

[tallpaul003]

Hi guys
Quick question: how many angelfish (species only tank) would be okay in a trigon 190 (bow front corner tank 190 litre)?
Thanks

I think maybe "5 or 6". I'm not sure but I think 190 liters translate to about 50 gallons. That should be just enough space to grow a small group of Angels to adulthood.
