Hey, I'm still rather new to keeping clams and don't have the experience to really have a great feel for what might be going on day-to-day with the animals. I bought a supposed maxima-crocea hybrid about a month ago, at the time of purchase is was an off-opal color with a fair bit of pink and almost-white blues. Under my lighting it has always looked a fair bit different, though at times it does show off a bit of its' old opalescent streaks, I'm running an AI prime do deliver around 250 Par to the rock it is on (5 or so inches below the water line). It's on said rock (really it is in a shallow hole) because it jumped off the rubble-peice I had attached it to and then totally-latched itself into a hole in the rockscape overnight and refused to let me budge it (I chose to instead rearrange the rockwork so it was as high as possible in the tank, but it still can't quite open all the way). With that out of the way I was hoping to get some advice, information, or opinions on the bands of brownish and pinkish coloration around the mantle. I've read that they're everything from normal, to acclimation which can take months, to LED hot spots, to localized bleaching or overgrowth of symbiotic organisms from too much/little light-nutrient-etc. At this point I figured I would just ask and see if someone with more experience might have an opinion. The tank is a 12g nano-atoll and has no nitrate or phosphates, is minimally stocked, and I do 5% water changes weekly- dose two-part - and keep the alk around 10.5. The second picture is the most-similar to the clams' appearance, to my eyes at least, in person. Thank you for your time! Oh and it can actually open a bit wider than in my pictures , I just can't seem to not spook it with the camera >_<
I bought and acclimated a "hybrid maxima-crocea" clam yesterday and put it in a nice low-direct-flow and brightly-lit spot about 8" from the top of the tank. It fully-extended within an hour and was displaying most of its' inner-mantle. However this morning I woke up and it seems to have scooted itself into a hole, its foot and the few thin byssal threads it had (from being stored in sand at the LFS) are openly-dangling down into the (1/4 or so deep) hole and, on top of that, it seems to have positioned itself in a place where its shell is partially-obstructed. It hasn't fully opened since then, though it still has fine color, shadow-response, and can open *most* of the way. (a bit wider than in the picture below, (you can see part of the inner mantle the lights going off spooked it) The main problem is that, when I went to move it, the bugger seems to have its' foot wedged or some new byssal threads down as it fought against me with enough resistance that I felt I would hurt it even if I just tried to rotate it. Should I bite the bullet and risk trying to relocate it to somewhere it might be able to fully-open and grow, or just trust that the clam has found a great spot for itself and see what happens? Also please excuse the lights-off camera-phone shot and diatoms, kicked up some dust and double-dosed two-part by accident, the cerith and nerites are having a great time at their new buffet though.
Not really sure what to make of this. The clam has been happy for almost four months now, but I just noticed yesterday that part of his mantle is retracted. These pics were taken last night and really no change today. Certainly doesn't look like PM, but I really have no idea what else it could be. He still reacts well and besides this part of his mantle, expands well. My other two derasas have shown no symptoms of PM either, leading me to believe this guy is possibly being irritated by something. Yet on that side of the shell, there is just some rock. I stared at him for about an hour last night, no parasitic snails, nothing picking on him, and I couldn't see anything inside the shell that could be irritating him. I'm really at a loss. Anyone ever seen anything like this before?
