Overview
Plating Montipora (like the classic Monti cap) frags with your fingers: the thin plates snap cleanly like a cracker, and every piece with living tissue will grow. Encrusting Montis need a chisel or screwdriver to pop a crusted chip of rock free. Either way this is the perfect first SPS to frag — forgiving, fast-growing, and cheap to replace if you fumble.
What You’ll Need
- Clean hands or bone cutters (plating), small chisel or flat screwdriver (encrusting)
- Frag plugs or discs and gel super glue
- Coral dip — Montipora-eating nudibranchs are a real pest; always dip both directions (new frags in, and inspect anything leaving)
Step-by-Step
- For plates: grip the plate edge and snap off a piece an inch or so across, or score and snap with cutters for a straighter line.
- For encrusting types: work a chisel under the crust edge and pop off a chip with tissue on it.
- Dip thoroughly and inspect the underside for nudibranchs and their egg spirals (tiny white coils).
- Glue the piece flat onto a plug or disc — plating Montis mounted flat re-plate upward in a natural shape.
- Return to bright light and good flow.
Aftercare & Healing
Montipora encrusts its cut edges quickly — within a week or two you should see the rim of new growth (often a lighter growth margin). Full plates re-form within months. If the parent colony shaded itself or grew into a neighbor, fragging the overgrown edge is also routine pruning.
What Can Go Wrong
White patches spreading polyp-by-polyp: Montipora-eating nudibranchs — inspect at night, dip repeatedly, and remove egg coils by hand. They are the number one reason to quarantine Monti frags. Bleached frag after mounting: too much light too fast if it moved up the tank; drop it lower and re-acclimate.

Frequently Asked Questions
How do I frag Montipora?
For plating Montipora, cut a piece of the plate with cutters; for encrusting types, cut a chunk of the encrusted rock. Glue the frag to a plug. Montipora is one of the easier SPS to frag.
Is Montipora good for beginners?
Yes. It is among the hardiest and fastest SPS, more forgiving of light and parameters than Acropora, which makes it a great first SPS to grow and frag.
How fast does Montipora grow?
Quickly under good conditions; plating types can add visible growth monthly. Give it stable alkalinity, moderate-to-high light and flow, and it encrusts and plates readily.
