A new type of coral frag holder has been introduced in Europe. The new coral frag holder is made out of a mixture of crushed coral rubble and then positioned together to form a frag. Like most frag holders this is also harmless to your aquarium as it is made out of 98% coral rubble and 2% epoxy resin. It will not release phosphate and silicate while giving a very natural appearance to your reef aquarium versus traditional frag holders. These are about as natural as we have seen yet. You can pick up a pack of 12 of these in Europe for around 8 euro or $11.
