cross bracing

Hi! I've been hung-up on this for a while and I was wondering if anyone could help me answer the question. I've already built this tank but am yet to put in any braces. All the glass is 6mm except the base which is 10mm I think euro bracing will look ugly and cause obstruction since the tank...

Was wondering if there were more then one kind and are they still considered one if they have cross bracing?
