Frogspawn Coral Starter Care Guide
A practical introduction to frogspawn coral care, including health risks, water quality, tank setup, food and behaviour.
Use this guide to notice and organize information. Contact a qualified veterinarian for medical concerns or urgent change.
About the Frogspawn Coral
Frogspawn corals are large-polyp stony corals with fleshy tentacles that end in several rounded or branching tips. Branching and wall-shaped colonies grow differently and the exact form matters when planning placement or fragging.
The expanded tissue is delicate and sits over a sharp skeleton, so rough handling and direct flow can cause tears.
Health risks to know about
Important concerns include rapid tissue recession, brown-jelly-like infections, bleaching, unstable alkalinity or salinity, copper exposure, skeleton damage and stings from nearby coral.
Spreading brown mucus, tissue lifting from the skeleton, ongoing deflation, a gaping mouth or rapid bleaching needs prompt expert help.
Tank, water and equipment
Use a mature reef aquarium with stable chemistry, suitable reef lighting, low-to-moderate changing flow and plenty of room for expanded polyps and sweeper tentacles.
Track salinity, alkalinity, calcium and magnesium. Place the hard skeleton securely and keep the soft tissue away from rock edges.
Food and feeding
Lighting supplies much of its energy, and small coral pellets or suitable marine foods can be offered when feeding tentacles are visible.
Pause strong flow briefly if needed, feed lightly and remove rejected food.
Behaviour, tank mates and enrichment
Full inflation and gentle movement are normal. Polyps may retract after a fish brushes past or during maintenance, then reopen once the disturbance ends.
Frogspawn can sting other corals, and some fish sold as reef safe with caution may nip its fleshy polyps.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature and salinity whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
