I liked the aquarium a lot. I did see several things that will need to be constanly cleaned or they will quickly get brown algae and fish will die. Thats the big problem with those salt water tanks. I bet they have very few original reef fish left. The fish inside the pyramid, too, were great about 5 years ago. Last time I went, they sucked. Spending all the time and $$ on the aquarium, I guess.
