Discoid Roaches
Discoid Roach Feeding Frequency Chart by Reptile Species
Feeding Frequency Depends on Age and Species
Discoid roaches work for nearly every insectivorous reptile, but how often and how many varies significantly depending on what you're feeding. Hatchling bearded dragons need roaches every day. Adult leopard geckos might eat every other day or less. A gravid female monitor has different demands than a juvenile of the same species. The chart below breaks it down by species and life stage so you can dial in the right feeding schedule for your reptile.
Bearded Dragon
Hatchling to Juvenile (0–8 months): Daily. Babies are growing rapidly and have high metabolic rates. Offer roaches as part of a mixed diet (insects + vegetables). Hatchlings will eat small discoids; as they grow, move to medium sizes.
Young Adult (8–18 months): 5–6 times per week. Growth rate slows. Offer medium to large roaches.
Adult (18+ months): 3–4 times per week. Established adults can go longer between meals. Supplement with vegetables heavily at this stage.
Note: Bearded dragons can become reliant on roaches if fed them constantly. Rotate in other feeders (crickets, dubia, hornworms) to avoid repetitive strain and to provide dietary variety.
Leopard Gecko
Hatchling to Juvenile (0–12 months): Every other day or every 3 days. Hatchlings and young juveniles are growing but have lower metabolic rates than bearded dragons. Offer small to medium roaches as part of a varied insect diet.
Subadult (12–18 months): Every 3–4 days.
Adult (18+ months): 2–3 times per week. Mature leopard geckos are selective hunters and will leave food if not hungry. Feed appropriately sized roaches (medium is ideal for most adults).
Note: Obesity is common in captive leopard geckos. Don't overfeed. If a gecko ignores roaches at feeding time, skip that session—it's signaling satiation.
Blue-Tongue Skink
Juvenile (0–24 months): Every other day to 3 times per week. Young blue-tongues are growing actively and benefit from regular protein. Offer small to medium roaches as part of their omnivorous diet (mixed with vegetables and occasional fruits).
Adult (24+ months): 2–3 times per week. Mature blue-tongues prefer a higher proportion of plant matter to protein. Don't overload with roaches; balance with leafy greens and squashes.
Note: Blue-tongue skinks are opportunistic foragers, not aggressive hunters. Some will snub roaches entirely and prefer stationary food like pre-killed insects or vegetables. Know your individual's preferences.
Monitor Lizard
Hatchling to Juvenile (0–18 months, species dependent): Every other day to every 3 days. Small monitors grow fast and benefit from regular protein. Offer small to medium roaches appropriate to the monitor's size and gape.
Subadult (18–36 months, species dependent): 3–4 times per week. Larger roaches are appropriate as the monitor grows.
Adult (36+ months, species dependent): 2–3 times per week. Some larger monitors (Salvator, Argus) eat fewer, larger meals. Smaller monitors (Ackie) tolerate more frequent feeding of medium-sized prey.
Note: Monitor age and feeding schedule vary dramatically by species and size. A juvenile Argentine black-and-white monitor has very different needs than an adult Ackie monitor. Research your specific species' growth rate and metabolism.
Chameleon
Hatchling to Juvenile (0–6 months, species dependent): Every other day. Young chameleons are visually hunting small prey and prefer variety. Small discoids work well mixed with crickets, roaches nymphs, and occasional dubia or hornworms.
Subadult (6–12 months, species dependent): Every 2–3 days. Offer small to medium roaches as chameleons grow.
Adult (12+ months, species dependent): 2–3 times per week. Most adult chameleons are picky eaters and prefer variety. Relying solely on roaches will eventually bore them. Rotate with other insects regularly.
Note: Chameleons are visual hunters and often prefer moving prey. Some individuals will completely ignore roaches if they've become habituated to faster-moving insects (crickets, roaches nymphs). Know your individual. Also note: chameleon species vary wildly in size and appetite (dwarf chameleons eat far less than veiled chameleons).
Size Matching Matters
Discoid roaches come in small (roughly 1/4–1/2"), medium (1/2–3/4"), and large (3/4"+) sizes. Match the roach size to your reptile's current gape:
- Hatchlings and small juveniles: Small roaches only.
- Growing juveniles: Small to medium roaches as they grow.
- Subadults and adults: Medium to large roaches, species dependent.
A roach that's too large is choking hazard. A roach that's too small isn't satisfying and requires more individual roaches to meet caloric needs. Get the size right, and feeding becomes efficient.
Adjusting for Individual Needs
These guidelines are starting points, not gospel. Individual reptiles vary in appetite based on temperature, seasonal activity, health, and personality. A very active bearded dragon in optimal conditions might eat more frequently than a lethargic individual in a suboptimal enclosure. A gravid female monitor will eat more than a non-breeding adult of the same age.
Watch your reptile's body condition. If your gecko is getting chubby, cut feeding frequency. If your bearded dragon seems constantly hungry and is still growing well, you can increase frequency. The chart gets you started; your individual reptile tells you if adjustments are needed.
Also remember that discoid roaches are one tool in a varied feeding program. Most of these species benefit from rotating through different feeders (crickets, dubia, superworms, hornworms, etc.) to provide dietary variety and avoid creating a picky eater that only accepts one food type. Use the chart to integrate discoids into your feeding schedule, not to make them the entirety of it.
