I understand that many will already have these corals. We tried to choose corals that would be affordable and hardy (as nano tanks can be a bit more challenging). You definitely can set up a tank as a non-contestant and create a build thread in this forum as part of the contest.

Not sure if I mentioned this, but the contest prizes I am working on include a 14 gallon biocube (overall best tank winner) and a Tunze Nano Stream 6025 (best growth winner). This is not firm yet, but those are along the lines of what the prizes will be.
