Hi Everyone
I'm looking for some advice on a stingray setup. I have been considering a stingray setup for around 24month now (not long

)
I am keen to get a setup completed as I now currently don't have any fishtank setup what so ever.
My problem is - I will me looking to move house within the next couple of years, so I have been considering a 5x2x2 for the time being.
I am looking to keep one of the smaller species of ray, such as Retic, Hystrix or Scobina (most likely Retic since they are most common). How long should I beable to comfortably keep a ray (or two?) in a 5x2x2 before having to consider upgrading?
Long term, size/expense is not really an issue, although just wanted to avoid moving house with a huge tank!
I have read that the Retic's/Scobina would confortably live in a 24" deep tank, or 30" - would this be sufficient?
