I am starting a saltwater tank and am waiting for it to cycle. I am also an ichthyologist so I have a strong background in fish biology and am increasingly annoyed with LFS pushing to cycle with a live fish and a bottle of beneficial bacteria rather than a fishless cycle. I understand the old way has always been to cycle with a fish, but we know that to be cruel now (even though folks still do it). What are others thoughts? I had a store employee practically insult me today for not wanting to use a fish to cycle so I am a bit miffed.
