So Petsmart has tank and hood/light combos for $2 per gallon right now, which seems a better deal to me than petco since you get the top. Anyway I have my two boys in a divided 10 gal and love it, but would also enjoy then having more space. I know a 20 long would be better than high but the stand I have isn't long enough to accompany the long tank. So I'm thinking about upgrading to the 20 gal high since an aquarium is all I can have at college and its a 20 gal limit. Ive previously had a 29 gal divided for bettas and the height didnt appear to negatively affect them in any way. What do you guys think? Is it worth it? Just seems like a good deal for the price. If anyone has done this before please post pictures, I'd like to see the finished product!thanks!
