How to feed your fry when away for a few days

Hey. My cousin wants to take a few of my fry and i've got everything ready for him (fry food, anti-chlorine, etc etc) and hes got the tank already. But then suddenly we just remembered that he's always away starting friday night to monday night. He'd go back with his sister to his mums house for the weekend on friday night(2 hours drive to another state) and would be back monday night(straight away goes to work in the morning on monday)

So then we've been thinking how he'd be able to feed his fish for the weekend. Kinda expensive to get an automatic fish feeder, and they're only tiny little fry. At about 1 month old and maybe 1cm big? (yeah I know my fry are tiny for their age )

So how is he gonna feed them? he was talking about getting one of those holiday food blocks, but i've read some bad reviews about them so i'm not so sure if that's a good idea.

The room temp water here is 30-31*C. and usually I feed my fish about 4 or 5 times a day maybe. Once when I wake up before I go for my work at 9am(part time before college starts :x) then my sister would feed them at about 1pm, then again at 5pm, and again at 9pm, then i'd return home at about 10 and feed them once more before I sleep. Their tummies don't seem like their bulging out anymore like they were before. So i'm not so sure if that's a good thing or not.

So, guys help me out here =/. What can my cousin do to keep them alive for the weekend?
(remember, they're tiny little fry and I read frys can't live a day without food.

And he's very excited about getting these little fishies. So I don't wanna disappoint him by telling him he should wait till they're bigger.

 

help would be appreciated guys

 

you can try getting something like this...it will release live food once they hatch continuously so that the fry can eat.

 

I'm not familiar with that product. With fry, you do need to feed multiple times per day. If something like Amazon suggested doesn't work, it might be best if your cousin waits to take charge of these fish until they are old enough that they can go a few days without eating.

 

and how big would they have to be before they can go days without eating?

 

Based on when I used to have kribs, my personal thought is at least 4 months of age.

 

ok thanks, I guess he'll just have to wait
