oh yeah and to all of you out there who see these pics and think(cool) i gotta get one,its not the greatest idea i had saltwater for a few years before i had gotten my first shark and that was mini,the brown banded,shes not so mini anymore well after the 55 gallon i thought i could get a 120 and she would be fine well i was mis-informed again so now im on my 500 gallon tank with just her and the port jackson and in order to finish keeping them im actually looking to put an adition on my house for them,with an inground pool,so remember this,(cool) sometimes costs more than most people are prepared for,like myself,lol seems i would have been better getting a lifetime membership to shedd aquarium
