Separating two axolotl after getting too big and not eating normally

[Chub-chub]

I had two wild type axolotls in a 20 gallon long until they got too big and I had to get another 20 gallon long they're about 8 to 9 in or so the tanks are both fully cycled but my female after moving isn't eating normally she eats half a big nightcrawler a day I was wondering if this was normal and not something to worry about or if I should worry about it any assistance would be helpful thank you

it may take time for your female to adjust to the move as it isn't uncommon for axolotls to refuse food for a while after a big disturbance.
