Chocolate cucumbers really are the ultimate critters for keeping your sand nice and clean. These are robust animals and are an essential part of any clean up crew. Colours can vary between cucumbers from bright yellow gold to a sandy colour. Whilst some species of cucumber are known to have the ability to release toxins into the water when stressed/dying it is extremely unusual for this type to cause issues. It is worth ensuring all circulation pumps are protected to avoid them crawling in and being hurt.
