    Hi guys and girls... need to know a bit about copepods...

    Good or bad for the tank??

    How would i go about getting hold of them? and then maintaining?

    Do they? and HOW do they even benefit the tank?

    any help is great help! :)

    copepods are actually bad for the tank.It depends.
    they attack small fry.they would not do any harm in a community tank but they will capture fry in a breeding get a hold of them i heard you could buy a maze kind of net to really capture them.well i would say they will not benefit the tank but they do help a little by eating diatoms,bacteria and single celled organisms in the water.
    i hope my answer helped!

    copepods are great for a tank. The detritus eating species will help keep the tank clean. They also are a natural food source for a number of fish, especially mandarins. Most people set up little breeding areas in their refugiums just to keep populations up. If you bought some chaeto or LR, you likely already have them in your tank. If not, you can buy culturing kits online from any number of sources, just google them.

    I have live rock in my saltwater set up.. and at night with the nightlight on, i see one or two quick centipede-like critters but with alot less legs! could this be them? their too small and fast for pictures.. *sob sob*

    Are copepods delicate? or a hardened species?

    Is their anything i should take note off when trying to get the population up? ei: like how coppers bad for inverts...

    time for some google action!

    centipede-like critters could be bristle worms(fire worms) and not at all Copepods..Copepodes look like flees in the tank

    Yes thanks, that is def them right their (just googled).

    By the sounds of it? they are good for the tank rom what i researched, any ideas how i can increase the population.. or will they just increase in good time?!

    Could i have both... copepods and bristle worms... or do they clash?!

    You can have both. Some people swear by bristle worms, others swear at them. Just be careful when moving rocks, when they get big, they can sting or bite, but it supposedly hurts a little. Some species of crabs eat them if you choose to get rid of them, or you can use traps.

    can bristle worms be found in freshwater?
    because my friend found 1 in his freshwater tank.

    Not sure, I thought they were only SW but I've never actually looked into it, just an assumption.

    And then they could be the mostly helpful amphipods as well.

    Here's a pic of one I caught in my Nano.

    Notice the high spirulina/algae content in its digestive tract.

    One of the largest I've manage to catch is up to 1/4" long.

    great thinking moderator lol! HIGH FIVE!

    lol@master, indeed you wasnt lying there!

    Hmm i dont think i will encourage their growth... in my display tank anyway, maybe in a ref where i ill have one huge piece of LR that i will never move haha. Dont fancy any bites thanx.

    I have another quick question... for anyone and everyone that could advise... :)

    I seem to be growing some sort of coral/polyp-like specimen, its like a passion flower in its shape, take no notice of any colours, just the shape... its stuck to a piece of LR, and so tiny i can barely see it with my naked eye so i cant get a pic yet... its a blurry white/transparent colour... now at the moment i have very basic lighting, well not powerfull/good enough to house the type of corals ive researched and have really taken a liking too, however this one seems to of grown from scratch.... it was in a place (on this LR - still is attached) that has about 50% shade and 50% light, so its getting light but not brightly lit (low light conditions)... should i leave it where it is? to grow... or should i relocate it to a place with more enhanced lighting conditions? ive 2 t5's that light the tank...

    thanks guys n girls!
