Looking to get back into hobby with 6 ft tank - tank depth 18" vs 24"

I am shopping for a 6 ft tank (125-210 gallon) and am undecided on the depth of the tank I would like. The space I will be setting up the tank in is a wall with an inlay of a little less than 10" so I was debating how far I want the tank to come out into the room (it's to bad the inlay isn't deeper so I could have the tank flush with the adjacent walls but oh well...)

A tank with a depth of 18" fits better with the space I have but I could put a deeper tank in like 24" (get a standard 180gal) and it would work okay (just not as aesthetically pleasing). My last tank was an Oceanic 58gal which was a 24" deep tank so I'm a little concerned with going skinnier...


Anyway, what are you thoughts on an 18" vs 24" deep 6ft tank? If anyone has pics of the two size tanks post em up.


Thanks

Thoughts on a 150gal 72x18x29 tank? They seem fairly hard to find though (true?). From what I have found this would fit my space the best but it still raises the 18" vs 24" depth question...

 

i would go deeper. so 24". added depth will give u more room for aquascaping and keeping everything off the glass and sorta in the middle. will also give u more room on the sand for brains and scolys etc. more volume of water more stability.

 

I have a 120 48x24x24and a 90 48x18x24. And I love the depth of 24" I won't ever go smaller unless it's a frag tank only lol. Just makes doing rock work and leaving floor space so much easier

 

The more front to back space, the better for everything.

 

Agree with the above, the deeper the easier to clean the glass and more rock pieces would fit in. Would love to see how the tank looks once it's there, perferct space for one!

 

The deeper one, you'll love that extra 6"

 

Also I forgot to add that if you have a 6ft tank for sale shoot me a PM.

 

I'm in agreement with everyone else...you won't be sorry you got the 24" setup. Not only does it really open up aquascaping possibilities, but it gives your fish more swimming room so they aren't pacing so much as they can actually swim a circuit.

Finally, if you keep fish with exaggerated finnage such as lionfish, they will actually swim around more rather than perch, which is a complaint many folks have regarding them. It's all about space...

 

i have a 6' tank with 18" depth and have always regretted not going with the 24". As already stated, the extra room for the fish and the aquascaping is reason enough. Go with the 24.

 

I would think more depth would give you more space for various types of corals with different light needs. I'm confused though, you said skinnier but that would be width right? It sounds like those in the know are pretty consistent in recommending the deeper one....if the tank is gorgeous with lots of things to see, you won't notice whether it's flush or not just my .02.
