these pictures were taken last month, but the clams are in the same health. my lights did go out right after the pictures were taken, but i borrowed some lights from jynxgirl for the moment. i am planning on buying her old set up (130 gal tank), hopefully this weekend. my plan is to get them moved into that tank preferably by this time next month. then they will be under 250 metal halides. i'm not sure what the lighting is right now, but she said that they are strong enough that it won't hurt my clams or other corals. other than the lighting nothing has changed since i bought the tank back in sept. here is a picture i just took of my tank. it's not the greatest, but it'll give you an idea of what is all in it. http://i131.photobucket.com/albums/p...or752/1-17.jpg i was looking close at my rocks by the clams, and i can see little things moving around. they almost look like baby fish or shirmp? they are about the size of a pin head and are clear. i can't get the camera to focus on them because they are so small. the clam that has the light coloring on it has stayed still since i put it on the rock this morning, but the other one has moved to the other side of the rock since my last post. it seems to be trying to get away from whatever is crawling on that rock. i haven't put anything new in the tank since last month, so i have no idea how i would have gotten anything new in the water. my ammonia and nitrates were at .25 and 80 since i got the tank. i didn't know that was bad until last month when i posted a question asking about a coral i bought that just disintegrated, and was told that i should have my levels at zero. i've been doing small water changes and finally this past weekend got the levels to zero. now i seem to have trouble with my clams. could the change in levels be bothering them?
