30b vs 40b

I'm looking to upgrade my current 29 gal tank to something a little more shallow and with a better footprint. The 30b tank caught my eye, since it's roughly the same size. It's a very shallow tank at 12 in deep. The 40b has the same foot print, but it's taller. Does anyone have any pros and cons they'd like to share about these tanks?

Thanks!

40B's height and depth is a good balance. 12 inches in height is not a lot of room for stem plants once you add another 2-3 inches of substrate. Deeper tanks also allow you to scape better since the background plants can add better depth to the look the and feel of the tank.

What are you looking to keep and do with the new tank? I think that factors into whether you want and need the extra height.

I have a 12" tall tank (33 long), and I love it. But it also fits my needs (stream tank). I like how easy it is to get to everything. I love the somewhat symmetrical look since it's about as tall as it is wide. It fits well in the living room and leaves wall space for hanging art above. It's easy to light and keep plants happy because it's shallow.

Good luck.

40b because the aqueon are $40 at petco and new 30's seem harder to find

I have a 40b and love it (except for the fact I've already decided I want bigger but no room!) - I have plants that grow up to the top and I've only had it since February. Stem plants and my melon sword. The melon sword really could use a taller tank than mine.

I'd hate to "upgrade" to a bigger tank and only gain an extra gallon of water! If you've got the room I'd suggest getting the 40. I also feel like the 30 breeders are relatively rare? I'm not sure I've ever seen one in person and rarely hear people refer to them. That of course does not mean there is anything wrong with that style of tank.

I guess what I want to accomplish is a better footprint combined with a little shallower tank. My 29 is a little tall to grow the plants I'd like to have. I think with the deeper tank I could have more room for some better aquascaping action.

Plus, I'd really like to get some rams and I think they'd appreciate larger floor space.

Thanks for the suggestions, everyone! I'll probably end up with a 40b.

I was just at PetsMart today getting a couple Nylabones and I happened to look through their DPG tanks. Plenty of 40b's and 55's but I didn't see any 30's. Saving money is as good a reason to go with a bigger tank as any as if any of us needed one.

Definitely go with the 40B. The 30B footprint is a little bit odd. I can see having a 12 inch tall tank if you have like a 33 or a 20 long, but I think tanks IMO need at least a little bit of height.

Pick yourself up a 40B from Petsmart or Petco for 40 dollars. You'll love it. I did when I set my old one up.
