Sounds good to me
I've thought about getting some Rhinogobius myself but they seemed rather expensive in the aquarium shops near me.
Good luck with stocking up your tank!
I've done something similar like you, but a Vietnamese biotope. I keep the Vietnamese cousin of the White Cloud (Tanichthys micagemmae) along with Sewellia lineolata. At the moment it is planted with Vietnamese plants, but I'm thinking about converting it to a rock only tank and increasing the flow: http://www.aquaticplantcentral.com/foru ... otope.html Maybe you find this useful!
wow, your tank is amazing!
i post video's on my youtube page. the tank no contains rhino's, white clouds and loaches i'll put a piece of wood in it and then it'll be finished http://www.youtube.com/user/NickTheAnim ... ature=mhee
