In the 46g, no. Sorry dude. There are just so many other choices out there that are a better fit. Get the bigger tank first, then get the fish to put in it - not the other way around. It's a bitter pill to swallow sometimes when we get it in our heads that we want a certain something and we'll surely be able to "upgrade later" - but it's better for you, it's better for the livestock, and it's better for the hobby in general, when you do the right thing. We've all had to do it (ie. make some tough choices.) Stick with what you can do comfortably, and you will save yourself a lot of trouble.
