New Equipment for my Downgrade

[sillysidewinder]

am about to downgrade from my 25 gallon glass cube tank to a 12 gallon cube tank. Does anyone know of a good ~12 gallon glass cube that is reasonably priced? Also what would a good filter be for a reef tank that size? I am probably just going to use one of my Par38 lamps on it, or maybe two... I have a Crocea clam which requires a lot of light so I would probably just keep the spotlight on that with the 40 degree optics and change the other optics for 60 degrees. Would love to hear some suggestions, and I would also LOVE to keep it relatively cheap. Thanks ahead of time.

BTW, my corals/inverts/fish are as follows:

1 black ocellaris clown
1 orange ocellaris clown
1 small cardinalfish
1 peppermint shrimp
3-4 medium-large nassarius snails
3 crabs
1 crocea clam

hammer coral
duncan coral
zoos
palys
mushrooms
acans

Water Params:
pH ~ 8.1
alk ~ 9.4
calc ~ 420
mag ~ 1400
