I recently bought my first house, so my wife and I are excited to get our first aquarium together (I kept aquariums for 10 years from middle school through college). We are looking to get a 125 gallon aquarium and are trying to decide between doing a 'typical' Mbuna tank (just sand/Texas holey rock) or a fairly heavily planted one with tetras, coreys, etc. Living in Southern Louisiana means we get some powerful storms coming through. If we lost power for an extended time and stayed home, we would just use a generator to keep the aquarium running. My concern is if we decide to evacuate and power is lost - would one of these tanks do better than the other?
