Frag Faq:

How big should my coral be before I can frag it?
Well It obviously varies depending on the type of coral you are "fragging".  Mushrooms for example can be usually be fragged at the size you would purchase them at, although there is no reason why smaller specimens would react any differently. 
SPS corals such as acroporas can be fragged if the coral is large and healthy enough to snap off smaller branches of the coral colony.
LPS branching corals again just need to be big enough to divide the colony of branches into a number of smaller frags. If you aren't sure whether your coral is big enough to frag you can always check by logging onto the forums.


I am fragging soft corals but don't know how to keep the coral tied to a piece of rock, what methods could I use?
Corals such as toadstools, xenias and other soft branching corals can be tied down in a number of ways, Fishing line or cotton can be threaded through the base of the frag to keep a down, along with elastic bands or string.
Gorgonias SPS and other stony corals usually need to be adhered to rock using something such as Milliput or Deltec Aquascape.  LPS branches are usually best kept in the sand or in egg crate racking.


I want to set up a separate tank for coral frags, what kind of equipment is required?
A fragging tank can be a very simple affair, and the equipment you use will generally relate to the speed at which you can grow your corals as well as the health and sometimes colouration of your frags. 
A shallower tank is always better, as then lesser lighting can be used, and the shallow tank makes access easy for maintenance.  If you are growing soft corals then a basic setup with T8s or better is generally sufficient.
A skimmer is not always required, particularly if the water volume is sufficient for a regular water change to be enough nutrient export.  Water flow and fragments of live rock will provide the most basic method of filtration. An external filter filled with live rock is another good method of frag-tank filtering.
If you are planning to frag SPS or LPS then more equipment is usually a wise investment, namely a calcium or kalk reactor to create a consistently higher level of calcium in the water for corals to use.
If you have any questions about a proposed tank setup then feel free to post on the forum and get some feedback.

I've got frags that I want to swap or sell on so that I can obtain other varieties of coral, what should I do?
Well the first place to try is by posting a thread on the Coral-Frags.co.uk forums.  Here you can sell any coral, inverts or fish that you may have to other reef keepers, just click on the Frag Forums menu link and log in!
If internet trading isn't your bag then your next port of call is probably your local fish shop.  Usually shops with reputable marine departments are willing to take in coral frags in exchange for store credit or sometimes cash.  It is generally accepted that you should get about a third of what the shop can sell the coral on for, so you may get less this way but it all depends on your local shop's pricing.
And finally there are auction sites that you can sell your frags on, although we would prefer that reef keepers out there would support each other directly or else support their local fish shop.

Got any info you think other fraggers should know about?
