Who Gives A Fish Forums

hello everyone,
i'm hoping someone can offer some advice, i've got a 4ft marine tank with a mimic tang in it and i'm thinking of adding a yellow tang to the mix,
i'm really keen on getting a yellow tang as i've got loads of green weed growing on my live rock and i think it would help with that,
anyone have any experience with this, thanks

the green weed could be due to excess light causing algae growth, worth lookin into that before addin another tang
