How many fish is good to get a 75 gallon tank started cycling? I know too many is bad and not enough is not going to produce enough waste to start a bacterial growth. So tell me everyone, what do you think? Thank's everybody.
how many is too many?

One fish will do the job, but what size fish are we talking about?
Do you already have a fish tank in the house that is cycled? A far better solution to using fish to cycle the tank would be to put the filter for the new tank on the existing set up tank for 2-3 weeks. Remove it and put it on the new tank with fish, its cycled!

just go get a few mollies or dollar fish about 3 or 4 and let them do what they do best in less you have another tank or have one nearby that you can burrow some key necessity items from it to get you tank completely cycled in just a few days
^ agreed. go to your local lfs and ask if you can have some of their est. bio media, and use that in your new tank. it will cycle a lot faster and innocent fish will die

If you use fish to cycle your tank... when your tank is "fully cycled" it will only have enough bacteria in it to manage the waste created by those fish...
So if you cycle your tank with fish... and it seems to be cycled... then you add more fish... your tank will not be "cycled" to manage the additional waste created by the additional fish...
But if you do a fishless cycle... you can easily create more bacteria than a full stock of fish will create... so that when you finally do add your fish, there will be no 'spikes' of any kind... other than the slow accumulation of nitrate which is the sign of a cycled tank...
use the chart like one inch of fish per gallon also make sure to check ur amonia and all the other levels
