There are basically two ways to have peacocks -- breeding groups of 1 male to several females. Or an all male tank with no more than one peacock of any one type and none that look similar (Even if of different types.) So two eureka red peacocks in your tank is not a good idea in the long run. You could do a eureka red and a blue neon or a sunshine or whatever, but not something that looks similar. Even a ruby red can sometimes be trouble with a Eureka Red.
You should also understand that peacocks cannot live in a 30 gallon for the long term. You will either need to return both fish and do something different or plan to upgrade in the future to at least a 55. You might want to check out the library's cookie cutter suggestions for a 30 gallon to see what's feasible.
I would get a new thermometer.
Use Prime as a declorinator
Yes, you could do a 20-30 percent water change. Do NOT mess with your filter at this time.
I personally only feed New Life Spectrum cichlid pellets with a spirulina flake. You can read fish food reviews to get an idea of what people like. Do not overfeed.
I buffer my water with Seachem's Malawi buffer. But depending on your tap water and if you have coral substrate and limestone you may not need to do that. Your pH as it is is fine.
Since it appears that you're relying on your LFS to test your water, I strongly encourage you to buy the API master kit of liquid reagents so you can monitor your water accurately yourself.
Hope this helps! Good luck!
