advice on mixing fish

hey guys right now i havea brittle star, a yellow tang a diamond goby, 2 perc. clowns a fire goby a blue devil damsel {im trying to catch right now lol} and a few shrimp in a 55 gal tank. and im thinking about adding a few new fish and were wondering if they would mix well just because ive heard different things about mixing different fish. since i have the yellow tang should i be worried adding a copperband butterfly to the tank??? ive always heard when you have a tang you dont want to add another tang or butterfly that has the same colors. so i just wanted to make sure it would work. then i wanna add a blennie to the tank, not sure what kind yet but was wondering if that would be a issue with have a diamond goby in there right now. he and the fire goby get along great but they are not simular in size, so i didnt know if that would b a issue. and last are there any triggers that would work in the tank?? i know they are more aggressive so i wasnt sure if they would work or not. thanks for any help, there are a few other fish that i plan to add but i know they are fine to mix. if anyone has any good ideals or cool fish i should add let me know. want to make sure im not missing out on anything lol

pm lordraptor01 he would know.
also heres a sw compatibility chart

i wish i knew more about sw fish lol. do you have a top on your tank? my diamond goby jumped out last night. post some pictures when your done with the tank :D

same here

Sometimes those charts are not correct. I have mixed some Angels in my tank, abd once they got the pecking order in place, no fights what so ever. Its alll about territory.

lol well guys thank for the chart. ill get some pics up once i get everything going with the new guys.

hey guys so i went ahead and got the cooperband butterfly, and the yellow tang will back up and whip is tail at him. i have never noticed it before but he also does it to my diamond goby. he doesnt nip at anything. just does that. does anyone have any ideal wtf is going on???

your tang is attacking your butterfly. those little white barbs on the side for the yellow tangs tail are razor sharp and are for defense and also for attacking other fish.

basically you already have a big no-no as it is with the yellow tang in a 55 (or any tang in a 55 for that matter) tangs get large and it is not recommended that you keep them in tanks under 100 gallons.

second, your brittle star green? if so i would get rid of it or your perc, green brittle stars are fish eaters.

ok well thank for the info. ya he is green and has not ate any fish yet. im doing a pretty good job tryning to have bigger fish than he can take down (like chromies) and i do have a 100 gal tank in storage i just do no have to room to set it up, so i made sure to get small fish so they do have time to grow. i did have the size of these fish in mind when i got them and made sure i had time to let them grow. but lord do you think that yellow tank will calm down since the butterfly just went in today? thanks for any info
