I get that, so maybe they should chime in and let us know their ethics instead of just a broad statement in the TOS.
I will line some out for myself.
Killing crabs as they are considered "bad" - Not ethical to me.
Killing aips as they are considered "bad" - Not ethical to me.
Using fish or other critters to control the above - Ethical to me.
Taking an out of the blue mean fish and euthanizing it - Ethical to me
Fragging Corals - Ethical to me
Cutting anemones to make more - Not ethical to me
Recycling corals to feed my general stars and then put them into my CaRX to be reused by the tank - ethical to me
Throwing corals in the trash - Toss up, as I can easily see both sides.
Killing flatworms with chemicals - not ethical to me.
While arguments could be made for and against the above, these are my views and only my views.
Not a bad take, but if it is ok to add animals to eliminate the pests, why would manually doing it be any less ethical.
I bring this only as I have used peppermint shrimp, and copperbanded butterfly for aipstasia control. Also aipstasia-X.
The copperbanded did an outstanding job, yet after the aipstasia were gone he too passed. I was more afraid that he would start in on my corals, so I was going to move him from one reef to the next and end up in one of my fowlers, but he died.
Would love to get another as I still have aipstasia in my other reef, but I feel that it would be wrong (unethical) as even with my experience I’m just not sure I can sustain the fish so my eliminating the larger aipstasia and letting the shrimp manage the smaller ones seems to make sense to me.
I find people throwing away corals away because the grow too much really sad, but if there is no market for them as frags, or no way to get them to a store that needs or wants them, it seems no different than trimming trees or the grass for the overall health of the coral or system.
So I don’t think anything in your list would be considered ethical or unethical.
Now I don’t know for sure but I assume (butt/u/me) that what the Forum Moderators are referencing is gross negligence or intent.
Dumb examples -
Telling someone to add a cup of bleach to their tank to kill algae DON’T DO THIS IT WILL KILL EVERYTHING *disclaimer. This would be unethical.
Starting a thread with the intention of “starting an argument”. Then degrading people who react.
Intentionally lying to someone to create a negative outcome. Would be hard to prove, but say a very experienced reefer (determined by the knowledge in their other posts/threads) then starts telling new reefers, “Sure you can add 15 fish to your 40 gallon breeder as soon as you set it up. Just change 10% of the water and double dose Prime every 12 hours.” Again this would just be wrong as an experienced reefer would know that the fish are going to die.
IMHO the ethical consideration in the TOS have more to do with our communities interaction with each other vs our particular reefing habits. I would also assume that posting about raising fish to kill so you can get new ones, or “bragging” about not maintaining a tank to the point of “harming its inhabitants” would fall in here also.
So follow the golden rule. Do unto others as your would have them do to you.
