My bf and I are looking to buy a bigger tank for our dear fish. We have successfully kept a 6 gallon tank going for 7 months now. We are looking at the Biocube Coralife Tank but can't find many reviews. Do any of you have experience with this one? We realize the older version of this tank didn't do so well after a while. Also, if not this tank, would anybody have any suggestions on another tank in the 30 gallon range. We have a hammer coral, clown fish, cleaner shrimp, many hermit crabs, some snails, and an arrow crab. So we don't have much yet, but we love what we have and we want to give them a better home!
