My teen guppy fri can't close his mouth don't see anything in it he is skinny so he hasn't been eating his brother and sisters are always full and plump I separated him and did a water change in my tank 10 gallon 3 adult males 5 three month olds and 10 oneweek old babies sadly mother dead bc of my stupidity I separated her to recuperate and a break from the males.... I live in a attic,second floor so when its hot its hot when it cold its freezing long story short we had a freak cold front i had the windows opened it summer...and I put her in a hermit crab mini tank_thing and she froze not literally .....what should I do with my little guy?im scared to put him in the tank

is the tank cycled, heated and filtered?

Is it possible to get a closer picture of the mouth... does the mouth look normal and just open?  Does it look at all like part of the mouth is missing (possible mouth rot)?

It could have some food lodged in it? does he chew? Or Maybe he dislocated his jaw.

 

[Guppyxtina]

My tank is heated and filtered
