I don't have first hand experience with glasscages but know people who have their tanks. Some have better than others.
I wouldn't pay the extra $ for the shipping and custom pricing for a 50 gallon. Save the $ and get the 40 breeder. If you are patience, there are 50gal out there. They are older tank but much better quality glass (IMHO
). I see one advertise on CL
in my area all the time, unfortunately they are asking too much.
