ok i have decided to order a banded shark egg..i am going to first set up a 125gal tank,,any ideas on what filtration i should use and what fish i can put in the tank while the egg is in there?? so i am first gonna cycle the tank and put a sand bed and some live rock in there, than after the cylce i want to add the egg and if possible some other fish to keep the tank lively untill the hatching..any ideas?
