need help feeding my water dragon

[contos]

i bought a pair of eastern water dragons a few months back. theyve settled in fine but they hardly ever eat. i offer food every two-three days and they only occasionally eat. theyre starting to get a bit thin now. theyre not lethargic but im a bit worried they wont be fat enough for winter. should i move them in doors to feed? thanks
