The cycle on my 75 gal is complete. This is my first fishless cycle so forgive my ignorance. I am feeding the nitrifying bacteria with ammonia until Thur or Fri when my LFS gets new stock in. Everything I can find on fishless cycling indicates its best to introduce fish all at once or you wind up effectively cycling with fish until you achieve the full bio load. My problem is I cannot get all the fish I want at once. I live in a small town and I can get only what the store brings in. I can preorder, but no guarantee they will get what I want in the next shipment. I will have 32 fish when done, but will probably get 12 at the most for the first stocking. Whats the best way to proceed with a partial stocking or am I worried for nothing?
