Old Guppy?

[GuppyGirl20]

I was wondering if anyone could tell me how to tell if a guppy is old? I have this one guppy and started acting strange (there's a thread in tropical fish emergencies called Guppy Being Weird if you want to take a look (it was about another fish but that one died but I posted on the same thread since it was still the same thing [a guppy acting abnormally]). This guppy's color isn't as bright as it use to be and he is a lot bigger than my other two so I was wondering if that meant he was old.

Could be older, do you have photos? I have had guppies for about 4 years and am fairly good at telling age.  Also I need to know what you feed them and tank size and temperature

It's a five gallon tank. I feed them flake food on the week days and freeze dried brine shrimp on the weekends and I have started feeding theme a pea on Fridays. I use to just have a plain ol' florescent light which could get the tank water over 82 but I just a few days ago got a different kind of light for my plants and a heater to keep the tank at around 78ish.

Is his tail always closed like it is in the photo?

 

[GuppyGirl20]

Yes his tail has never really fanned out.

 

[bluesword23516]

He could be older because of the size.  Maybe try fasting them one day a week. I guess its about two years old, maybe a little more. It appears to have full coloration and looks healthy. All I can say for sure is its sexually mature, beautiful fish.

You have nested brackets in your post which don't close properly ((())) . This is a programmers nightmare.
 
I'm only pulling your leg though.
