Four Days Alone Too Much?

[SunnySkies]

Ok, so, my tank is towards the end of the cycle (ammonia and nitrite stay below 1ppm even if I miss a water change for a few days) and I was curious.
 
Would my betta be alright being by himself for around four days? I'm getting dragged to my grandpa's house for christmas and won't be around for around four days to keep an eye on him. He's looking a little lethargic (no other symptoms), but I'm blaming the fact that the house is so cold at the moment and my heater isn't one of those fancy ones that you can control the temperature of. (It's around 79* F atm, I liked keeping it 80-84* at school but... eh.)
 
 
 
Anyways, excuse my rambling. Will he be ok for a few days or should I prep a 1gal tank to take along?

What size is his tank now?

Should be ok.

 

[SunnySkies]

2.5gal. Doing a 50%~ water change now just to get him ready for the week.

How long has the tank been set up for and been cycling?

 

[SunnySkies]

Ah... Set up and cycling since around Nov 24th.

 

[Blondielovesfish]

Should be alright then.
 
Just make sure to do a 100% water change before you leave and again as soon as you get back.

Alright, thank you!
