nice choice of fish.
i know it was already raised, but sooner or later it would be better to take out those fish that have the potential to grow much larger.
in addition, something for consideration is that those archocentrus may potentially hybridize if you happen to lose one half of the pair *touch wood*... the fish in that family are really similar. this can of course happen with fish that are not as closely related, but just something for consideration.
nice set up.
