I am going on vacation for 10 days.
I have 6 fish tanks in which I have housed 1 Arowana, 1 Flowerhorn (full size), 1Tetra tank, 1 Dolphin, 1 Chichlid tank, 1 Turtle tank.
I purchased 1 digital auto feeder which is working fine but cant purchase more (as of now) due to low budget, so can anyone guide me what to do.
Arowana feeding wont be a problem as I will get feeder fish for him, turtle also not a problem.
1 Fish tank I can install food timer. Rest 3 is question what to do.
Anyone knows easy way of DIY food timer?
I googled and came to know that fish can live 3 weeks without food, so need confirmation.

Personally, I haven't starved my fish longer than 3 days, but yes even I have read they you can safely leave them unfed for couple of weeks at most. But I ensure I give them a treat (like boiled egg whites, frozen brine shrimp) when I resume feeding after a gap.
Hope this helped.

Normally most of the fish survive for many days without food. They can go to snooze mode and return back to normal upon receiving food.
But since your fishes are used to feeding regularly, and 10 days is a longer duration, try to see if anyone can come and feed your fish in between, for at least few days (alternately).
Most importantly, than food, what must be taken into consideration is the water conditions. overfeeding or some issue with water happens and no one is there, it might be major issue for their survival in your absence. Also in case you are having someone to feed them in your absence, make sure that they don't overfeed and contaminate the water.
And try to avoid the week end food (ball type, hard in nature), I had a real bad experience with it and lost one fish.

Thank you guys for response,
Situation is I recently moved to new place so can't trust neighbours as of now.
I am thinking to make packets for each fish tank for one day and will ask my parents to come at 5th or 6th day and feed. as they used to do the same earlier when i used to go out of town. So no chances of overfeeding

Do a minor water change one day before you leave. Do not feed any food from that day onwards till you are back, condition being you are coming back within a week.
The second condition for one week being you are a average fishkeeper.
Seeing from your profile, you have been around since 2006 which means you are experienced and keep clean water and feed your fish appropriately, meaning you are a good fishkeeper. Then you can not feed your fish for 15 days and still find happy fish when you get back.
Disclaimer: Not sure about Arowana and Flowerhorn together. Also assuming your bio-load is as per wisdom.

They should be fine without food for a week, even 10 days doesn't seem like much. Its not as if they regularly get the same amount of food in nature. However, seeing as these are not wild fishes, It would be advisable to reduce the amount of food in a consistent manner. And similar to what the experts have suggested above, I would recommend a small water change(around 15%). I'd like to add that feeding feeders is not a very advisable either. You never know what kind of ailments the feeders may pass in to your fish. Unless of course, you've quarantined the fishes beforehand or you get them from a trusted source.Its a different matter altogether then. The turtle should be more than fine in my opinion. From what I've read reptiles go into a sort of snooze mode . BTW, you mentioned that you've got a dolphin as well . Im sorry if I sound like a noob but are you referring to the river dolphins of the ganges or is it a common name for some other freshwater fish?. Anyway, Happy fishkeeping!!

Personally i have starved my fish for 5 days without food as i had gone away and all fish were fine. I do have plants in my aquarium. As suggested make sure you do a water change a day before you leave and don't over feed while leaving.
If you are still worried get weekend block. It will cost around 100 bucks. I don't know if fish eat it but i had gone out for 7 days and i used weekend fish food block. I have around 14 fish in the tank and all were alive. I placed weekend block near air pump.

If you have a heavily planted tank, then can do without feeding fish in that tank for 2-3 weeks. There'll be enough microfauna for them to feed on. However you can't leave the lights off/on for 2-3 weeks.
