Wowsers! Yeah..you're in that oversocked range...sry. Impulse buys...they get ya all the time don't they? I've been showing great restraint of late myself as the past couple of times I went to our LFS they have had hillstreams. Grrrrr....and I don't have a river tank setup.

As for kuhlii's....my personal fav (after the rays)! Love these guys. They should actually be kept in groups of 4+ and would greatly prefer a sand bed. Extremely active little buggers at night. You can get a small actinic light and turn it on when it's dark and you can enjoy them more.
