Gap between eyes8mm
Feeding goal

Rule of thumb: prey should not be wider than the space between the eyes. Babies stay strict; older animals may suit longer soft or narrow feeders when the width is still sensible.

Measured bands use published livefood size-guide data where available. Rows marked approximate are practical shopping bands where a referenced product page does not publish a measured length, and rows marked not stated are shown for completeness but are not used by the finder.

Repeat the right size

Once the size is right, make feeding predictable

New keepers usually start with smaller, more frequent orders while the animal is growing. When the feeder size settles, a livefood subscription keeps the same favourites arriving on a rhythm you can pause or change.

1Test the sizeUse a small order first, especially for babies and nervous feeders.
2Pick the rhythmWeekly suits fast-growing or high-appetite pets. Every 2-4 weeks suits steady routines.
3Adjust as they growMove up a band only when the current size is taken confidently.
