Was very happy today about the net on my powerhead-came down and found my little sea cucumber ( which was originally a hitchhiker and really tiny-about the size of a swollen pellet of fish food) stuck to it -no harm done at all- otherwise there would have been bits of eviscerated cuke all over the place. is now about 1.5cm in size-haven't seen it since my post about it in my nano tank journal. Getting rather fat as well
