wow thanks everyone for your replies and suggestions. i have a great feeling about this forum! this is my first time on a aquarium related forum.
to answer some of your concerns
i have the stock power compacts that came with the nano cube 28g.
i also agree the fish dont belong in the nano cube, but my wife insist she wants the tangs when we visited a LFS
over the weekend, i had no choice but to take them home...
i don't plan on leaving them in there for long though, i'm already searching for a 150g+ tank setup.
and about the cubic puffer i mentioned earlier, it's actually a cubicus boxfish....
i have some concerns about my tank, i hope you guys can tell me what's wrong..
the bigger naso blonde tang isn't very active, he likes to hide behind the live rocks and he doesn't come out to eat, but since we just got him for 2 days, and the lfs
told me it takes a few days for the naso blonde to get used to the new tank.
the clown fish is getting a little weird, he used to be active and swims all over, and when we first got the anemone, he swims near it all the time. now he just stays near the top around the left nozzle, and he's not eating.
the small blue tang and the boxfish are the most active, they eat a lot and go everywhere.
the anemone, (not sure what it's called, its got red base and pink tentacles) i can't figure out if it's doing ok, it kind of buried half of itself into the sand. i tried moving it a few times onto the rocks but the current always move it away and end up near the rear of the tank.
