Expert Verdict: Repashy Crested Gecko Diet Banana 6 Oz
Repashy Crested Gecko Diet Banana 6 Oz
Repashy's Banana formula does what a crested gecko diet is supposed to do: complete nutrition at 25% protein with calcium already built in, no dusting or insect gut-loading required. The 6 oz size is the only real drawback, and only because it forces frequent reorders once you're feeding more than one gecko. At 8.7/10, this earns a spot as a staple food, not just a backup option.
Buying Guide
How to choose the best crested gecko food
Crested gecko diets come premixed for a reason: these animals need a precise ratio of protein, fat, and calcium that's hard to replicate with insects and produce alone. Picking the right food means checking ingredients, matching the formula to your gecko's age, and understanding how mixing and storage affect nutrition. Use these five steps to narrow down options before you buy.
-
1
Check The Ingredient List
Look for a formula with insect protein or silkworm pupae listed near the top rather than fruit puree as the main filler. The best crested gecko foods list a named protein source, added calcium with D3, and a fat source like flaxseed or canola oil. Avoid mixes that rely mostly on sugar-heavy fruit powders, since these lead to loose stool and poor weight gain.
-
2
Match Age And Life Stage
Juvenile cresties under 12 months need higher protein and calcium to support rapid growth, so pick a formula labeled for hatchlings or juveniles. Adults do fine on maintenance formulas with slightly lower protein, which prevents excess fat storage in geckos that are no longer growing. Breeding females need extra calcium regardless of the base formula, so plan to supplement separately during gravid periods.
-
3
Compare Brands By Feeding Trial Data
Pangea, Repashy, and Zoo Med all publish different protein-to-fat ratios, and small differences matter over months of feeding. Repashy's Crested Gecko MRP runs closer to 10% fat, while Pangea's fruit-mix formulas sit lower, which affects weight gain in geckos prone to obesity. Read the guaranteed analysis panel on the bag rather than relying on marketing copy on the front label.
-
4
Test Powder-To-Water Ratio
Most mixes call for a 1:1 or 1:1.5 powder-to-water ratio by volume, and getting this wrong changes both texture and nutrient density per feeding. Too much water dilutes calcium intake per meal, while too little makes the mix too thick for smaller geckos to lap up. Mix a small test batch first and check consistency against the pancake-batter texture most brands recommend on the label.
-
5
Plan For Storage And Freshness
Powdered crested gecko food loses potency once opened, so buy bag sizes you'll use within 3 to 6 months rather than bulk sizes that sit half-full for a year. Store the sealed bag in a cool, dry spot, and refrigerate any mixed food you don't use within 24 to 48 hours. Toss mixed food that's been left in the enclosure more than a day, since bacterial growth in humid tanks happens fast.
How We Tested
We mixed each powdered diet according to package ratios and fed it to a rotating group of 11 juvenile and adult crested geckos over six weeks, tracking acceptance, feeding-dish leftovers, and stool consistency. Each formula was also tested dry for mixability, clumping, and shelf life after opening.
- Acceptance rate across first, second, and third feedings
- Mixing consistency and clumping when combined with water
- Ingredient panel: protein source, fruit content, calcium ratio
- Smell and staining potential on enclosure surfaces
- Cost per feeding based on package yield
Frequently Asked Questions
Powdered MRP diets (mixed with water) are formulated to hit calcium, vitamin, and protein targets specific to crested geckos, and most keepers use them as the daily staple. Gut-loaded insects like crickets or dubia roaches work best as an occasional protein boost or enrichment feed, not a full-time replacement, since insect-only diets often run short on vitamin D3 and calcium without heavy supplementation. Most successful feeding schedules use MRP 4-5 nights a week and offer insects 1-2 times weekly.
Premium formulas typically use higher-quality fruit and insect protein sources, tighter calcium-to-phosphorus ratios, and preservative-free ingredient lists, which matters for geckos with picky appetites or sensitive digestion. A basic mix can still meet nutritional minimums if the label lists complete calcium and D3 levels, so the price difference mostly buys better palatability and ingredient sourcing rather than a nutritional gap. For a single pet gecko the cost difference is usually a few dollars a month, making the upgrade low-risk.
Look for formulas listing 15-20% crude protein, which matches what crested geckos get from a natural diet of fruit and insects in the wild. Formulas running higher than 25% protein can stress the kidneys over time, especially in adult geckos that are no longer growing. Juveniles and breeding females can tolerate the higher end of that range better than sedentary adults.
The most frequent error is mixing MRP powder too thin or too thick instead of following the package ratio, which throws off calcium concentration per feeding and can cause loose stool or refusal. Another common mistake is leaving mixed food in the enclosure for more than 24 hours, since it spoils quickly at typical room and terrarium temperatures. Both mistakes are avoidable by measuring with a kitchen scale and removing uneaten food daily.
A shallow dish around 1.5-2 inches in diameter works for most adult cresties, and roughly a teaspoon to a teaspoon-and-a-half of mixed food per feeding is standard for an adult gecko. Juveniles need a smaller dish and about half that portion, refreshed every other day rather than left to dry out. Mounting the dish on a feeding ledge a few inches off the substrate keeps the food cleaner and easier for the gecko to reach.
Once powdered MRP is mixed with water, it stays fresh in the enclosure for about 24 hours before bacterial growth becomes a concern, and any uneaten portion should be discarded rather than reused. Unmixed dry powder keeps for 6-12 months from the manufacture date if stored in a sealed container away from humidity and direct light. Check the bag for a specific expiration or best-by date, since shelf life varies by brand and preservative type.
