Practically perfect in every way
you have to remember though that a tank is far from the most expensive bit of kit you'll need. the filters, heaters, lights etc will be more expensive. I don't think it's something that's really worth cutting corners on. I'd rather go for something a few inches wider and deeper to give them that little bit of extra room. Fair enough your fish might not get to 18"..... but if it does??? are you seriously gonna be able to give him up and take him back to teh store cos your tanks not big enough..... i'll bet not, so I'd say get something that's big enough for worst possible scenario.
If your 13 and strapped for cash your gonna have to face facts you'll need to save up for a while to get good enough filtration etc, so just save up a little while longer than planned and get a slightly bigger tank.
