Tweeti have alot of experience with them. grew up in a house hold with 15 tanks at one time. salt tanks can be very hard to get set up. the hard part is getting the water cycled so that it can support life. it took me 6 months to get my 75 gallon workin right, then i lost them all in a fire. i'm going back to fresh water with some large carnivores. alot of fun watchin them eat and easier keep.
