Aberrations in giant clams are not unheard of but they are few and far between. There is one extreme example of a bicolor maxima clam from Tamotu and Reefkoi has previously had a gold foil maxima clam but his latest bicolor maxima clam is sporting a really strange color anomaly. It appears as if part of this bicolor Maxima clam’s mantle is lacking the usual pigment and the only thing we are seeing is where the zooxanthellae is growing.
This two and half inch long bicolor maxima clam has been in captivity for a few months during which time the color pattern has held. We’re not married to our hypothesis of what’s going on to make the mantle of the bicolor clam appear this way so feel free to share your theory in the comments.[ReefKoi]
