Though smaller as far as gallons, I found a 38 gallon aquarium at petco with everything included (most of which would likely need an eventual upgrade), it is 20 inches high. It is a comparable price after I pick up hood and heater, not to mention all the other odds and ends included in the tank. I'm still trying to decide then of I should get the 40 or not. I suppose it all depends on if the shop is giving the free large filters away with the smaller open top tanks. I could theoretically pick up a ten gallon, get the largest filter, and then add it on with the 38 gallon filter. I've got to call them tomorrow anyway to see if they will take my platies, so I'll ask before I stop by. I didn't get anything from the petco today.
