Ardentiella Scarlet

Ardentiella sp. “Scarlet” are a striking tropical isopod known for their deep red colouring and very active behaviour. They are fast moving and love to explore, often climbing bark and wood around the enclosure. Once settled, they are a fantastic display species and a great addition to a more advanced isopod collection.

From my experience, this species does best when kept warm with good airflow and plenty of natural materials in the enclosure.

Difficulty

Advanced

Ardentiella species can be a little more sensitive than beginner isopods. Stable humidity and good ventilation are very important for keeping them healthy and breeding.

Temperature

I keep my Ardentiella Scarlet between 22–27°C.

Warm temperatures help keep them active and encourage breeding. If temperatures drop too low they may become less active.

Humidity

They prefer high humidity, but it’s important to maintain a moisture gradient.

In my setups I keep:

One side of the enclosure moist

The other side slightly drier

This allows the isopods to move around and regulate their own moisture levels.

Ventilation

Good airflow is essential for Ardentiella species.

I recommend enclosures with plenty of ventilation or cross-ventilation, as stagnant air can lead to moulting issues.

Enclosure Setup

These isopods are very active and enjoy climbing, so providing a natural and varied setup works best.

My enclosures usually include:

Deep natural substrate

Plenty of leaf litter

Cork bark for hiding and climbing

Pieces of rotting hardwood

Moss to help hold moisture

Leaf litter should always be available as it forms a large part of their diet.

Substrate

A rich substrate mix helps create a stable environment and also provides food.

I typically use a mix of:

Organic soil

Decayed hardwood

Leaf litter

Moss

Adding a calcium source such as crushed eggshell or cuttlebone helps support healthy moults.

Diet

Ardentiella Scarlet feed mainly on decomposing organic matter.

Their diet should include:

Leaf litter (always available)

Rotting wood

Fish flakes or dried shrimp for protein

Vegetable scraps

Occasional isopod food mixes

Calcium should always be available to support shell development.
