Being the wife of a military man definitely deserves thanks from everyone. You have all the respect in the world from me--I have no idea how you could do it. My daddy was in Desert Storm, and I had a hard time dealing with his being over there...I can only imagine what it was like for my mother, with a preschooler and an infant son. I wasn't even old enough to understand the real risks of war. I just can't imagine it now. You must be very strong.
Now for the question at hand...I agree with Ophiura, I think you've really done all you can. IMO, as long as your fish seem to be doing well, don't worry about them. They could very well just be extremely hardy...or maybe they're mutants.
Either way, if the ammonia doesn't seem to be bothering them, I wouldn't worry. Just keep a close eye for signs of stress; heavy breathing, erratic swimming, scraping on the rocks, and signs of ich, which can be brought on by stress.
IMO, just don't add any other livestock to your tank. I don't know if you have any corals or inverts, but they're much more like to be harmed by poorer water quality than fish, so keep an even closer watch on them.
Also, make sure to do water changes often. I suggest you get a rubbermaid tub or something of the like and throw a heater and powerhead (or even an airstone--that's what I use, but I only have a 29-gal and change 5 gallons out at a time) to age the water you'll be using for changes. From what I've read, most people let the water aerate and circulate for about 24 hours before doing a water change.
Sorry for rambling, I tend to do that when I'm tired.
Best of luck to you, and thank you again for what you AND your husband do for our country.
