A true yellow-bodied leather from Fiji, far more demanding than the common tan toadstool and prone to melting if conditions slip.
Keeper tips for this variant
Needs strong, stable lighting and pristine water to hold the yellow; it is notoriously sensitive on import, so quarantine and acclimate slowly.
