Additional advice

Divide the “Feed quantity per day” over at least two feeding moments per day.
The diet should be rich in fiber and low in starch and sugars.
Seeds and grains (including wheat and oats) should be limited as geladas easily exploit these nutrients and can become overweight.
Insects can be supplemented occasionally.
Supplement a diverse selection of vegetables (read more about differences between vegetables).
Provide less palatable food in the morning, when hunger is greatest.
Feeding in bowls is not recommended.
Stimulate foraging behaviour by hiding, stacking or hanging the feed. Examples can be feeding puzzles, tubes, hanging boxes and/ or scatter feeding (read more about feed enrichment and foraging behaviour).
