    small cylindrical particles in my tank.

    I just started a new reef tank, all I got in the tank is live rock, 2 damsels and a bit of hair algae. I see some detritus on the bottom of the tank (no sand in the tank yet) and there are a bunch of small green cylindrical things about 1 mm in dia. and about 5 mm long with a slight curl to them, they look like plastic pellets but they crush easily and so they are soft. I don't think it is fish poop since there are too many and also damsels don't poop out pellets I think. They seem to be dead in that they don't move. What are they? Some sort of worm castings or?

    Could be some sort of die off from the rock. Without a pic it's to hard to say.
    I take it that your cycling your tank using the Damsels right? If so have you ever heard of a *fishless cycle* Just wondering due to my concern for the fish

    well I had my rock in a dark trash can with seawater, powerhead and heater for about 5 months, now I am starting my tank again. the rock should be in pretty good shape, nitrate and phosphate are reading zero. i can try to post a picture.

    What are you feeding the fish? Algae pellets? That would probably turn their detritus green.

    I am feeding the damsels some formula I pellets. I think maybe it is fish poops. I will do an ammonia test on it, good idea. Maybe I am noticing it cause I got no sand in the tank yet. The cylinders were not hollow in the microscope so I don't think they are worm castings. Fish poop, good idea. the amount of the cylinders is not unlike the amt of food i have feed to date and the fish are about the same size. Well thanks pandora 32, that is the best crap idea I have heard in a long time!
