No problem. Another place to check out for aquariums is called King Ed's pet centre and aquariums. It's a maze in there but they have a wearhouse way in the back, through the outside courtyard via their down stairs, full of aquariums of all sizes. You may be able to see what they've got for refurbishing, or if they'd deal on some of the tanks. They're in Burnaby... it's a strange shaped blue building on a funny little corner. Might be worth a look.
http://www.kingedpet.comAs for merauke vs northern, go with what you feel comfortable with, for sure. I believe you are likely correct when you say much of the research out there is based on wild caught animals. But personally I think alot depends on the personality of the skink itself regardless of subspecies. I have three meraukes who are puppy dog tame, and I've not made any efforts taming them, it's mostly just how they are, very easy going and just as lovely as skinks get. Two of the three are imports. The rest of mine range in between freindly and shy, but they have all come to me with very different backgrounds.
I suspect handling as youngsters will have something to do with how skittish they are as adults as well. Northerns will have been handled from day one, where as most meraukes or indo species do not get handled untill they are finally put into circulation after being imported, that's a fair amount of baggage to overcome for a wild animal turned pet. Two of my very tame animals are imports, but both as babies, so they were handled from a very young age. That's all just speculation on my part ofcourse, it's very difficult to say the exact reason.
In the end I can tell you some are shy and others beg to come out whenever I walk into the room and I think that could be said about Northerns too.
Best of luck in your search!
