What should I do?

Do a nice big water change 2 days before you leave, and feed lightly before you go. They will be fine for a few days with out food and feeding them less before you go means they will poo less while you are gone, leaving the water less dirty.

Do not give them a nice big feeding to hold them over -
1) they will poo a lot, dirtying the water.
2) they may become constipated and you wouldn't be around to help them.

Do not use food blocks -
1) they are gimmicks designed for fish and pollute the water more than they help feed your pets

Do not throw a bunch of feeder fish in for them to feast at will -
1) they ofted die with in a few days and their rotting bodies will quickly foul up the water
2) they are often diseased and one diseased fish can infect your whole tank.

Great info Jenna.

Pekams: Did you ever get a response to this question? What's wrong with my ADF?!
I don't have an answer but hopefully someone will chime in.

Thank you! although I have not got a response, the thread has disappeared and my ADF behaviors well now! So I think the thread should just be its faeces.

Thank you! you help me very much. Only two ADFs live in my tank, and I just feed them living bloodworms, instead of feeder fish. btw what is the lowest temperature that ADF can bear? 20℃? or lower?

If your frogs are taking pellets or reptomin get an automatic feeder, you can find them for feeding cats, slight modification may be required depending on the model also set the feeder up with a small amount of food, just enough to tide them over.

Automatic feeders, unless you have one that is tried and true can be risky - - there are many many stories about them malfunctioning and dumping all of their contents into the water at once - - this can lead to gorged frogs that die from over eating or/and massively polluted water from rotting left over food.

Agree, have read of many horror stories regarding automatic feeders in my 48 years of fish keeping. Do what Jenste recommended in 1st reply and frogs will be fine. Juvenile & adult healthy frogs (and fish) can go 1 week without food OK.

If you have filter in tank, do clean media (with tank water) during water change. I just shoot a stream off siphon hose into media while holding it inside pail used for water changes. Good luck!
