all these fish are compatible
im not getting all those tangs, just a few from the ones listed
bluethroats and niger are the most peaceful and can be kept together. i have a niger now and hes a wuss
the wrasses are fast but arent actually aggressive, i have now an adult male paddlefin
snowflake eels, again not aggressive, i have a juvi at the moment
porc puffer, they just want to eat! kept with large fast fish porcs are no problem
harlequin tusk may look ferocious but they are not and will do fine with the fish i listed.
yellow tailed blue damsels are the most passive of damsels, also considering there is no one they can bully in my setup other than themselves.
they are fast enough to not become a snack. i know several people that keep smaller damsels with large aggressive fish, so yes this will work. three striped is another possibility. you need to do your damsel homework

it would be suicide to add the damsels last after other large fish have been added, then for sure they will become a meal.
yes damsels go first, they are the smallest and least aggressive for my setup. your supposed to add the most aggressive fish LAST, and im my case the least aggressive are the damsels.
who would add a $179 dollar harlequin tusk first??? its just non sense
not sure what you mean by a big plain tank? suggesting that these fish will kill each other? well thats not the case, do your homework and look around at other large aggressive tanks. the fish i listed are the norm and very compatible.
when i say non aggressive for this fish list it is due to the fact that they are not aggressive with fish their own size, a few shoves here and there but no bloodshed will occur, they are NOT reef safe
and KODIAC you obviously are not a pro, not even knowing the benefits of a bare bottom tank????
so your comment will be taken with a grain of salt.
do you have an aggressive FO setup???
