Flatworm predator?
Our hammer coral has been receeding for a couple of weeks, previously having been very healthy. Finally took it out and had a look at it, to find 2 large (2cm) planarians. Does anyone know if these are harmless and feeding on necrotic tissue - or did the d**n things cause the problem?
You can find a photo uploaded to the "critters" part of the photo gallery
Thanks for any info
