I have a Crocea Calm that is in my 34 gallon mixed reef aquarium. It has recently sprouted fibers on the clam shell portion just underneath the mantle. I can easily pull them off the shell. They are only growing on one side of the clam shell. I can easily pull of the filament like fibers, but have no idea what they may be, and don't want to hurt the clam. The clam appears healthy. I have done many searches on the internet and these forums with no luck. I have attached a quick iPhone Pic for your reference. The Pic is in my dark office, making the sand around the clam appear to be dirty due to the low light, and nighttime LED
Water parameters are all normal.
Nitrates less than 5
I have LED
(Ecotech) lighting and good water flow. All of my LPS
and two SPS
corals are doing fine. I use a Kalk
solution in my RO
My livestock consists of two clowns (Black & White | Orange & White Percula) which are paired, two chromis, a Diamond Goby and the typical CUC for a tank my size.
I am not all that worried, but more or less curious as to what these may be? Unless of course, you tell me otherwise!
As always, any advice, answers, suggestions or feedback is greatly appreciated!
