How long does a starfish need to survive in your tank before you can assume safely that it's eating and not starving to death? I have a few that have been in my tank about 14 - 16 months now depending, I presume it's safe to assume those starfish are doing fine?
(they're bigger than the used to be, and the one with a missing leg is regrowing it slowly but surely)
No question this happens, I know quite a few people who disagree with the low survival rate, but it's low, not impossible
Yes, I would have thought they would have perished by now....Cool!
