Trimming corals question

[Delphinus]

Colts are easy to cut - the tricky part is getting the cut piece to attach to a new piece of substrate.

One method is put the cutting in an area of low flow (even inside a small bucket of some kind) in the tank along with rubble and let it reattach on its own.

Another method is stick a toothpick in the bottom and then elastic or fishing line over the toothpick over rubble. Usually elastic or fishing line over the coral itself just cuts the coral more and doesn't work so well for reattachment.

There are other methods too.

There is probably some risk in that the cut could introduce an infection to the coral .. other than "use a clean razor blade" I'm not sure what to suggest to minimize that risk.

good luck!
