I am not sure why people think it is "ok" to scream "tang police" at anyone who suggests it is a bad idea to house fish that have a low tolerance for conspecifics in the same tank. You immediately diminish your position when your only argument is the "ocean is bigger" or "others do it". A person has the right to do whatever they choose with their tank, but this is an educational forum. If someone is making stocking choices that may not be successful, please do not take offense when someone suggests an alternate plan. It is not personal, it is to educate aquarists who may have an honest desire to house their fish in the best environment possible. If that is not the goal, I am sure people will move on to those who aren't just looking for confirmation that they are doing the right thing.
