Breeding crested geckos require a lot of preparation from your end.

You need to have the right incubation medium, the right environmental conditions, and the right tools to measure and monitor the environment of your crested gecko eggs.

One such important requirement is the right kind of substrate. This substrate should be such that it promotes egg-laying behavior in female crested geckos.

Zoo Med Eco Earth compressed coconut fiber substrate is available in the following variants:

  • Single Brick
  • Bricks pack of 2
  • Loose packs

Why it’s great for Crested geckos?

  1. It is eco-friendly and ideal for terrariums that require moisture retention.
  2. Being made of coconut fiber, this substrate is good for odor control.
  3. It is digestible and your crested gecko won’t be at risk of impaction even if it accidentally gets a mouthful of this substrate.

Mushroom Substrate

  • Contains the perfect ratio of Premium Manure, Vermiculite, Coco Coir, and Gypsum.

Mushroom substrates are not available commercially. Instead, when you opt for bioactive terrariums with bioactive substrates.

You will come across mushrooms every now and then. This is virtually harmless – just keep a check on the moisture content of your substrate and enclosure.

As long as the humidity level is ideal and the substrate isn’t too wet, don’t worry about the mushrooms.

Mushrooms in your substrate will act as natural cleaners. They’ll decompose fecal matter and any residual food.

Moreover, they will convert this decomposing matter into nutrition for plants.

So, it will be a win-win situation for your mating crested geckos as they won’t be bothered by the need of replacing substrates frequently.


Josh’s Frogs BioBedding Tropical Bioactive Substrate

  • Cleaner environment for your pet due to the bioactive cycle, decreasing the risk of bacterial disease

It is bioactive, and thus, is more expensive than other substrates – and it comes with additional benefits too.

Why it’s great for Crested geckos?

  1. When used with microfauna and isopods, you will not need to change this bioactive bedding for years.
  2. It provides a naturalistic appearance for the terrarium.
  3. The bioactive cycle will keep the substrate clean by decomposing fecal matter. This will reduce the risk of infections for your crested gecko.
  4. It retains the right amount of moisture for the substrate to be comfortable for your gravid female crested gecko.
  5. It promotes egg-laying and ensures safe and comfortable breeding.

BabiChip Coconut Substrate

  • BabiChip bedding is ready to use — just add water for expansion and increased humidity.

This is one of the most hassle-free, dust-free, and clean substrates that you will find. It is easy to clean and maintain.

Why it’s great for Crested geckos?

  1. You can use it for both desert geckos and crested geckos. For your crested gecko, you will simply need to add water to the substrate. For desert geckos, you just need to directly add it to the tank.
  2. A unique benefit of this brand is that you will get a hassle-free return or replacement if there’s a problem with your pack.

Orchid Sphagnum Moss

Orchid Sphagnum Moss
  • This once living moss has been dried after being harvested instead of being collected after dying like peat moss. 

Orchid sphagnum moss is an excellent substrate for crested gecko tanks. It retains moisture and is breathable.

It does not cause waterlogging inside the tank as well. Additionally, it provides a good burrowing surface for gravid female crested geckos.


Substrate Buying Guide

Some important points to take care of when buying substrate are given below.

Tank Size

Depending on the size of your crested gecko tank, you should provide enough substrate for mating and for laying eggs.

In fact, you also need to provide a separate egg-laying spot within the tank to ensure that the female crested gecko feels comfortable laying her eggs there.

Moisture and Humidity

A gravid female crested gecko is going to be fussy and selective about the substrate on which she lays her eggs.

If she does not feel comfortable, she will refuse to lay her eggs.

And one important factor that can lead to such refusal is the lack of moisture in the substrate.

If a female crested gecko does not get a sufficiently moist substrate, she may reabsorb her eggs.

This is because sometimes, eggs may have delicate shells. When a delicate shelled egg is laid on a dry substrate, the chances of survival of the egg are very low.

So, you need to ensure that the substrate you choose for your crested gecko eggs can retain moisture.

Hygiene

Your gravid female crested gecko will lay her eggs about 30 days after mating.

In that period, you need to ensure that the substrate does not interfere with the hygiene of the tank.

Otherwise, your female crested gecko may fall sick and it will lead to unhealthy eggs.

Cleaning and Maintenance

You should ensure spot cleaning of the tank on a daily basis.

The best kind of substrate for cleaning and maintenance is the kind that does not hinder spot cleaning.

Moreover, the substrate material itself should be such that it does not rot.

What Do I Put In The Bottom Of My Crested Gecko Tank?

There is a wide variety of substances you can use as a substrate for your crested gecko. Some of the popular choices include:

  1. Moss
  2. Coconut bedding
  3. Paper
  4. Mosses
  5. Soil
  6. Wood shavings
  7. Bark

You can choose whatever works best for you and your crested gecko.

Is Loose Substrate Bad For Crested Geckos?

Yes, a loose substrate is often bad for crested geckos. You should avoid using a loose substrate with nonbiodegradable particles like sand.

Such a substrate, when accidentally ingested by your crested gecko, can lead to impaction.

Instead, go for substrates that are easily digestible and not very fine.

This will prevent impaction and any other respiratory problems that can arise when loose particles are inhaled.

How Often Do You Change Crested Gecko Substrate?

Depending on what kind of substrate you use, it should be changed weekly or monthly.

If you use bioactive substrate material such as soil, you will need to change it monthly.

This is because bioactive substrate materials can recycle fecal matter and thus act as a natural cleaner.

On the other hand, substrates like paper need to be changed on a weekly basis because even after spot cleaning daily, all that fecal matter inside the tank will eventually ruin the hygiene of the paper towels spread inside.

Is Coconut Fiber Good For Crested Geckos?

Coconut fiber or coconut husk is a nice option for use as substrate in a crested gecko tank.

The particles of this substrate are easily digestible.

So, even if your crested gecko accidentally gets a mouthful of coconut fiber, it won’t suffer from impaction.

Additionally, coconut husk acts as a natural resistance to fungal and mold growth. It also absorbs foul odors.

Is Reptisoil Good For Crested Geckos

Reptisoil is a substrate made by Zoo Med – a pretty well-known brand when it comes to equipment and food for crested geckos.

Reptisoil is made of peat moss, soil, sand, and carbon. While it is a pretty good substrate, it has its pros and cons when it comes to crested geckos.

Pros of Reptisoil for crested gecko tanks:

  1. Easy to use.
    It is one of the most hassle-free substrates to use. You simply need to add it to the tank without much fuss. You will, however, need a drainage layer.
  2. Holds humidity.
    One of the most important measures of the quality of a substrate is its ability to retain moisture. Reptisoil can hold humidity and maintains the moisture level well. It does not dry up easily.
  3. Promotes breeding and laying behaviors.
    If you are looking to breed your crested geckos, you can opt for Reptisoil. It is great for laying eggs and your female crested gecko will feel quite comfortable with this substrate.

Cons of Reptisoil for crested gecko tanks:

  1. Expensive.
    A DIY substrate will be cheaper than reptisoil.
  2. Not safe for juvenile or baby crested geckos.
    With sand and soil particles, a juvenile or baby crested gecko will be at risk of impaction if it accidentally gets a mouthful of the substrate.

Summary

When breeding crested geckos, you need to ensure that the substrate is comfortable for laying eggs.

If that doesn’t happen, the female may not lay eggs and instead reabsorb them.

The best substrates are those that retain moisture without waterlogging, provide a burrowing surface, and are easy to clean and maintain.
