here's my tank so far...its been lots of fun.
i got the tank, a 12g eclipse with rocks and sand from craigslist for $50. I spent $50 on the lighting upgrade(32w smartpaq), $20 digital coralife timer from ebay, $30 for some garf grundge and the coral frags and they threw in the mangrove and chaeto for free

, cycled 2 weeks and everything looked good. I got my fish(
six line wrasse) from my lfs a couple days ago. not to much money spent...small tank on the (relatively) cheap....
I had tons of bristle worms and pods but the wrasse ate most of them in 2 days, im sure there are some pods hiding out in the algae...
I have a little cleaner crew I got for free from a friend - 2 smalls hermits(one red legged and one blue legged) and 6 narissus and 2 turbos snails....
I have spotted a
sand sifting star too...and some weird things growing here and there
In the future I want to get a 33 gallon tank to make the wrasse happy, I plan to drill the eclipse and convert it to a refugium to go above the display tank...
