Question: When to start feeding every other day?

I've searched through the forums and haven't really been able to find anything that really answers my question. I may be blind or something, but whatever I figured no harm could come from making a more recent thread.

I wonder because it seems that my axies have lost their appetite. I usually feed them every evening and they swim to the top to greet me and eat until they're full. Now, they just sit at the bottom and don't really even try to eat. I finally managed the transition to salmon pellets about a week ago and they were LOVING them.
They are about 3.5-4 inches long now.

My leucistic will normally eat one or two pellets before just turning his head away all fussy-like. My wild-type, on the other hand, barely even tries to eat. I can usually get him to eat one... but failed this morning. He'll open his mouth just a tiny bit and if the food doesn't go in he just gives up. And he's been staying in really inconvenient areas of the tank, making it harder for me to feed him.
I have been trying to feed them in the morning and the evening again because I'm worried that they're eating too little... so they're having a total of 2-4 pellets each over the span of a day versus the 6-8 they'd eat in one go before.

So my question is if it's just that time to feed every-other day? Is that why they are not as hungry (and also more lethargic since that happens as they grow)?
Or are they still too small for that and therefore there is some other underlying problem?

At that size, you can feed them every other day.

By limiting food availability, they'll probably eat more readily. They'll be hungrier, so they'll snap at food better.

I was told to start feeding every other day when the lotl was full grown. Basically, when the lotl stops getting longer and starts getting fatter.

What is the temperature of your tank? I've read at very low temperature their metabolism slows and they eat less.

Kaysie, thanks! I will start doing this then!

Kat, it's actually at the higher range of acceptable axie temps... just below 70 F (20 C). It's a HOT summer.

Perhaps it's the heat? Swarley was not hungry and lethargic during a heat wave. However, as long as your in the right temperature range, I wouldn't worry.

try something wiggly for a bit, as an apatite simulator maybe?
