Color: The Cucumber (Red & Black) has a pink and black, red and black color.
Size: The Cucumber (Red & Black) may grow to 12 inches.
Diet: Omnivore.
Feeding: It likes to eat Eats algae and detritus on sand.
Behavior: The Holothuria edulis is generally peaceful toward other tankmates.
Care: Many consider the Holothuria edulis a medium-maintenance specimen. venemous, it will secrete poisonous membranes if scared or dies.
Lighting: Has lighting needs.
General notes: The Pink and Black Cucumber is supposedly known as `the edible cucumber`. We do not advise that you try this. Sifts through sand, digests algae off of it, and expells out clean pellett shaped sand that breaks back down into clean substrate. Be careful with copper-based medication and extreme nitrate levels. Holothuroids are the odd-Class out in being secondarily non-radial appearing; often looking like strange ornamental sausages, some translucent, others opaque and warty. Cucumber-like! May excrete poison membranes if it dies. In the event of death do several large water changes and place carbon in a net mesh bag near a filter source to help remove toxins.
Water parameters: Keep water quality high (SG 1.023 - 1.025, pH 8.1 - 8.4, Temp. 72 - 78° F).
Origin: The Cucumber (Red & Black) is commonly collected from Hawaii.

Not a pink and black one, but we had a very small yellow sand-sifting cuke that started climbing the glass a lot, thought that was odd.
Came home from work one day and all 14 of our seahorses were dead. Cuke was laying in the middle of them with its guts hanging out.
There's a thread on reef central about a guy that had a pink/black one in a very large tank, I think 240... and on Christmas it nuked his tank.
These things should be boycotted.

i have a medusa worm that im dealing with right now. it just climbed down my overflow tube last night before i could get a hold of him. i expect to come home from work today and find him in the filter sock.
as for them being toxic, other than sea apples, you really dont have to worry about them nuking the tank. they have 3 defense mechanisims.
1. push the water out and create a tough skin layer.
2. expell their digestive system
3. excrete their toxins (holothurin)
it takes a lot to make them get to number 2 and 3... only 3 being toxic. the holothurin is not directly toxic to your fish. the issue is when its excreted it will kill many inverts which will inturn cause a re-cycle in the tank and the high ammonia, nitrites, and nitrates will kill your fish. if you suspect something is wrong, test your water and most of the time it can be taken care of with a large water change (50% or so). there are lots of people who keep them with no problems.
