I have a zoa colony on a clam or an oyster possibly? i've seen it open and recorded this video, how do i keep it alive and happy?
is this even actually an oyster? it reacts to light instantly
Possibly a thorny oyster in the Spondylus genus (not all of them have the super long thorns). NPS bivalves, even large ones, require minuscule 2-20 micrometer particles, so most foods cannot support these organisms (for reference, the smallest rotifers are around 50 micrometers, copepod nauplii (babies) are around 100 micrometers, baby brine shrimp are around 300 micrometers, and Reef Roids are around 150-200 micrometers). These guys primarily subsist on phytoplankton (I hear daily dosing should suffice, possibly more frequently).It's some sort of mollusk for sure.
Filter feeder so you won't need to do much other than feed your tank.
Cool find
The more popular Tridacninae giant clams (Hippopus and Tridacna) are photosynthetic so they don't require feeding. NPS bivalves vary heavily in their care requirements, especially due to their feeding habits, with many hitchhiker bivalves being able to survive without much attention while Limidae flame scallops never seem to last long.Dose phyto and you'll be fine, think of clams in people's tanks....don't over think it
