I love my 12 gallon aquapod. Works really well and I like the lights on it. I can keep any basic coral in it.
Corals-frogspawn, 2 brains(one lime green and one red), zoos, bubble, candycane, mushrooms, GSP, sun polyp.
other invertabrets- 2 feather dusters, coco worm, snails, hermits, shrimp, crabs.
The levels pretty much stay constant in the tank as well. The only thing I changed in it was the arm to the powerhead. Originaly it didn't have the extented arm, it was just a fan shaped extention- didn't despense the water flow evenly! But with a quick inexpensive change it is way better!
A great tank all around. But now I want to upgrade to a bigger tank so I will be selling it!
