There is absolutely no reason to cycle a tank with fish in this day & age. You can fishless cycle a tank in a week to 10 days: http://www.**************.com/forum/library/water-filtration/fishless-cycling/

pussyfishhunter;2049012; said:imo that would be a good number of fish, i couldnt tell you how theyd get along in a 70. one other thing to consider is that some brackish fish need higher sg's as they age (scats for sure) progressing all the way to full marine in adulthood. others dont need this. i think the puffers are optimaly at 1.005 but dont quote me i dont keep em.
i personally would choose if you want a tank that is eventually going to be a high end brackish/marine or a steady sg and choose fish accordingly. just my 2 cents
