My new fish - worried about causing cycle issues

Not sure if I'm putting this is the right section or not.
My new fish I ordered have arrived...they're acclimating as I type.
I ordered:
1 Blue Ram
1 Gold Ram
6 Panda Cories
I got:
1 Blue Ram
2 Gold Rams
10 Panda Cories

So now I'm really freaking out about adding 13 fish to my tank all at once. I'm thinking I need to go get some TSS to attempt to compensate for the big increase in bioload.
Or should I just watch my parameters daily and do water changes if I need to?
Suggestions please. Quarantine is not an option.
I've worked my butt off (as most of you know from my whole crashed tank of the year experience) to get this tank cycled and to maintain it. It's been stable and I make sure of that. So I do NOT want any cycle issues.
Suggestions please.

 

It would probably be a good idea.
When I added 12 fish at once I used TSS.
There wasn't any cycling problems.

 

So if I add it do I not clean my tank or do water changes for the 2 weeks? Or do I go about my normal routine of weekly cleaning/water change?

 

I did a water change before adding the fish & TSS.
I watched the parameters for a few days, when I didn't get any spikes I went about my routine maintenance.

 

Well the fish are already in the tank. I was planning on doing a gravel vac and water change this weekend. Do you think I should stick with that plan and then add the TSS or should I just add the TSS and wait a few days to clean the tank?

 

I wouldnt do a water change right after new fish are acclimated. I would just add TSS and wait 2 weeks before another water change. Your fish won't suffer that much by just missing a few water changes.

 

Girlsbeforefish: that's what I was thinking. My tank looks really good right now and my parameters are normal. So a week or two without a gravel vac or water change isn't going to be too bad.
I think I'll just add the TSS tonight and wait the 2 weeks.
Thank you so much Lucy and Girlsbeforefish for your input and suggestions. I really, really appreciate it.
