sorry, but you don't know how resposible i really am when it comes to this hobby! for the past two years i've been trying to teach people to grow their own corals for the hobby. i've been growing coral for stores to sell to other hobbiest. not so much for the money, but to try and feel like my 0.00000001% has helped save some of the reefs that people are destoying for this hobby. i also make my own live rock for my tanks too. i sell it. but NOT for the money entirely. every time a rock is broken off a reef, it slowly kills an entire ecosystem. it really isn't good that stars are being used for food, but you know what, thats what they eat. at least the star isn't being hurt or killed. now, if those shrimp that only eat stars aren't being fed properly, THEY WILL DIE! just one more extinct animal in the world, right?
Many kudos to you, in all sincerity, for your work and dedication to sharing what you do. Perhaps you can see where your original post did not seem to demonstrate your concern? I stand corrected, and apologize.
But I hope you will understand that I am sharing what I do. I work on echinoderms, and there has been some discussion in our 'world' on what species are under the greatest threat and what those threats are. They are species that live in an endangered ecosystem, harvested to be dyed for crafts and souvenirs (and thrown out if they break in transport), and harvested for a trade where a huge majority will die from improper acclimation (a month from capture) and starvation (within a year of capture).
Sure, these shrimp may eat Linckia stars in the wild, but they do so very slowly- most of the Linckia bought for food will die much more quickly (and be replaced quickly) because they are not typically acclimated as needed (they are just food after all).
The idea of taking a chocolate chip and putting it in a sump to regenerate is not a bad consideration as well...at least chocolate chips will eat readily. I think rotating these guys in and out is a pretty good idea in fact, except that they are not reef safe Unfortunately, many reef safe stars will not recover from this sort of stress very easily.
Your post is similar to what I was saying above. I am saying that these stars are under a lot of stress in the wild, and that there are more reasonable alternatives for food when keeping these shrimp (freezing stars, using Asterina sp stars, etc) (and as an aside, I also have loads of these stars but do not keep SPS corals).
It isn't right to write off these stars, just as it is not right to do so with the shrimp. They will die in most tanks, just as these shrimp will if not given the proper diet. These stars eat algal and baterial films, and few tanks can support them long term even though they are imported and sold all the time. So I can turn this argument around....most people are not providing some of these stars with the proper diet. Is it OK if people buy them and they die in a month because they were just food for the shrimp (because ultimately they will die)? I guess, it is keeping another animal alive...best to make the most of the situation.
If people don't have the shrimp but want the starfish: does it matter if they don't have the proper food and the animal dies just because they are pretty, and can be replaced cheaply? Because this is common. I think you will agree, no. But because Harlequins will eat other species of sea star, that can reproduce quickly and cheaply, I believe it is more responsible to go with that alternative.
I want people to buy shrimp and stars and be responsible about keeping them; to consider and research before they buy. I think we are on the same page here.
And, BTW folks, don't know where anyone got the idea that I think it is cruel. It is the instinct of the shrimp to do this, and they take their time with it to keep the star alive as long as possible. But don't compare this to a wild situation. Those stars die faster in captivity than in the wild. I am simply saying that one should put a bit more thought into what
kind of star is used, or to make the most of each star by freezing it (which ain't too kind). Please don't make me out to be a bleeding heart. After all, I'm rooting for my green brittle to take out my 7 year old damsel. That would be pretty cool to see.
