Thanks! Actually, the 50 g is 2+ yrs, before that I had a twenty g for a 1yr and before that a 12g nanocube for a yr. Everybody moved from tank to tank to tank. Only thing that has changed it the water. hehehehehe
I have a crocea clam, anemone crabs, harlequin serpant star and various snails ( including an astrea (sp?) snail I've had for 4 yrs), plus lots of microstars, pods, bristle worms, tube worms, etc. No fish that would bother a cucumber.
So you think a cuke would be ok...where is a good place to buy one?
