community tank idea, crazy????

[octane99]

Hi all,

I need some advice on stocking a small community tank. 

I have a 30 gallon long tank and i want to make it a small community of a few types of tangs.

I use to have a big coloney of Multies a while ago and i want to get back into having tangs. 

i have fish in mind for the new tank but im not sure if its too many fish or if they would mix well.  Im only looking for the multi's to breed all others i want no fry.   below is a list of fish i want:

4 Multis (obivously there will be more very soon)
2 Caluvus (will two males live in peace or do they fight amongest them self)
         I know the Calvus will grow too big, but since they are such slow growers i hope to have an upgraded tank for them by the time they reach that stage.
1 or 2 Julie Trans Golbie (can two males live together or will they fight?)
1 BN Pleco (if not this then just a bunch of MTS for algae control)
1 Bricardi (i have heard they are mean when breeding but what about a single?)

is there too many rock dwellers? territory issues?

Any help would be appreciated

thanks
