since i changed over to lps-sps corals & started zeovit i run my fish down. i have a blue cheek goby, pink spot goby, scooter blenny, black & white humbug, a 2 striped purple wrasse, 5 fish all together 3 shrimp most fish won't last much longer as i want rid of them. l no my tank is'nt huge, its 25" H 24" W 32" L with all equip in sump. thats why i can't buy a adult sohal to large for my tank, but a 3" one will be ok for a while. mfinn is also correct about aggresion, but iv been told purple t are just as aggressive. i had another look at the fish in question today & was happy, i prefer a small one to a adult i find its exciting watching them mature i'm trying to change tank to lots lps-sps & just a couple of really good specimen fish i also won't stress out a animal for my asethetics, thats why i research first iv been looking into this for 6 months...
