I'm familiar w/how it works, I've known in my travels at that size to just add 1 or 2 at a time, wait a few weeks, etc, etc... but in this case it didn't work? I would have thought (unless there's some secret to salt water I'm not aware of) that 5 small fish in a tank that size (125 gallon) would not have had the sharp spikes that 5 fish in a 20 or even 10 gallon tank in which case I would think that was the issue.
In my experience, salt water fish are waaaaaay more sensitive to ammonia/nitrites then fresh water fish. It could be that since SW
is at a higher PH, the ammonia and nitrite have a considerably more volitile effect then in fresh water.
I made the same mistakes years ago when I started keeping FW
tanks. I figured that just adding them 1 or two at a time over the course of a few months and all would be well. I would lose a fish here and there, but didn't know at the time about the complexities of the nitrogen cycle. It wasn't until a I read an article on cycling after my tank crashed that I realized what was going on and how wrong I was with my assumptions.
I would honestly say that if your going to stick with SW
, that you need to become an expert on the nitrogen cycle and know how to test it to ensure its up and running.
