New to DBTC? Check out the information available here!

We have different sections below to place corals for DBTC, based on its rarity and difficulty level: Beginner, Standard and Extreme. These labels were not put into place to discourage people who are just starting out, but rather to ensure that, for example, a frag of some rare Tyree SPS which normally costs hundreds of dollars is propagated by someone who can and will return at least 2 frags back into the hands of other members who can do the same thing.

DBTC Rainbow/Rose bubble tip anemone
This category contains fairly common corals (non rare zoas, xenia, Kenya trees, etc.) These corals are ideal for members new to the hobby, as they grow well in newer systems or low light systems.

This category contains the majority of corals in the program, including SPS, LPS, etc. Members propagating this category of coral have a system capable of handling the coral they are asking for (i.e. established system of 4 months +, and satisfying lighting/water requirements for these corals).

Dbtc bonzi
This category contains rare or normally very expensive corals (for example, bubblegum watermelon chalice). Members propagating this level of DBTC coral have a system capable of handling any coral they are asking for (i.e. established aquarium with lighting/water parameters suitable for these challenging specimens).
