This will be my first marine tank. I went to Lfs
with a spec that included maximum size of 140*60cms, stating that i was interested in fish, soft corals and crustaceans. They have come back with a recommendation of a tank that is 140*60cms, and 90cms high (that's 36 inches). Generally, when i read around most tanks seems to be 24 inches/60cms.
Other than giving me more gallonage, are there obvious advantages to deep tank? It would be about 200 gallons, which feels...vast. What are the disadvanatges of 90cm depth?
