WELL...first I would get rid of the tang....seriously...a 36g is too small for it
then you have to decide what you want.....there are so many choices...firefish, clown gobies, ....A LOT of choices....lol.
i have a 36 bowfront. i'll tell you my future stocklist:
-my misbar clown
-flame hawk
-midas blenny
-sixline wrasse
-green clown goby
-pygmy angel
-blackcap basslet
7 fish is alot for a 36 but i have a 20gallon sump to add water volume and help keep parameters in check. it really just depends. but anyways, i made my stock list based on color and personality.
also...the tang has to go. your tank is way too small.
The Tang dosent have to go this moment... If its a juvi its prob ony and inch or 2... he is fine to have it for a little until it gets to big for the tank...
