Partner says I definitely need to get glasses as they are 3.5/4cm not 2.5cm!  :oops:  
 
Anyway, fish still alive to date; did my first water change (partner did previous) few days ago and i think I was more stressed than the fish! 
 
Also, now have small filter for the bowl (penn plax smallworld brand) which has helped a lot.

Will sort profile out in a few mins. 
 
Thanks for your suggestion to buy a cheap tank but after looking round it was much cheaper to get a tank made to our specs. , 80cm x 40 x 40, rather than buy one second hand.
