Nasty critters!
Hi,
I cannot believe I'm so out of luck! I'm new to the hobby but my adventure has started rather on its tougher end... The tank is 2+ months old, I have got two clowns, cleaner shrimp, few snails, two hermits an LPS and Softie. Few days ago I spotted something swimming lightning fast during feeding time. Becoming active especially with flakes over live/pellets. Goggled few things and started with isopods. Since I saw it during the day twice by now I ruled them out as night active. But then I noticed a mark on one of my clowns tail (something white-ish). Didn't look like something was attached more like a cyst. Because I did not see whatever it was for more than a split of a second size of their eyes was obviously impossible to judge. Flying blind I've made the trap as described in one of the posts - a jar with reversed top of a bottle + dead shrimp. I put there also mysis shrimp and flake food. Turned the lights down 10pm and after 10 mins went on with just red spectrum. This is what I caught... Needless to say it was so desperate to get into the trap that I have managed to take the jar out with it on... no net, nothing. Regarding people saying about FW dips, that's a No Go if you want your fish alive. I put it in FW straight from the tap with chlorine, added Coral RX and after 30 mins it did not look dead at all! Ended up flushing it. Decided to put the trap in again but nothing this time. Will try the next night and in a week as well. Not going to nuke my tank so hopefully it did not manage to reproduce yet (0.2inch max). Strange though it was active during the day, hungry? Anyone can tell was it a male or female? Regards, M |

I think its an isopod. They may "be nocturnal" but isopods run around my tank all the time. Possibly predatory?

As an amateur I could be wrong but it looks like predatory one. Since it is out the question which remained has it managed to reproduce and was it only 1. Probably arrived on LR but it was not here very long.
When I was cycling my tank instead of shrimp/fish option I went with kitchen ammonia reaching 2ppt. Seems not enough as well to kill it. Coral RX (for corals) and FW dip (for fish) of 5-10 minutes are also not effective, it would have happened no matter what was done as I put him through series of tests and it was alive after 30mins. |

So that one is removed, will set the trap next week to see if any more are here. Meanwhile new guests have just moved in... apparently black sponge is their hub but happily move all over the glass too. I did not see them until today with 25% water change done yesterday.
Fish are all over the place and seem to enjoy this time, good pods? |

Not sure but given your previous find i'd wager its more of the isopod sp. Im 100% not an expert though so second opinion is advised |

It is maxed out what may camera was able to do + mspaint. They are like a grain of sand, attach to the glass and love black sponge in the corner. This time the same picture without mspaint zoom... pls. not a farm of isopods, anyone?
No go for any live rock/sand in my next attempt... |

This is what i typically see^ (shape and size seem different in the photos you posted) But if they look like the vid you posted then ya those are copepods. |

I took another picture and there appears to be a lot of them!
Now I'm not so sure anymore, it is not so round shaped toward the head. Plus some of them look like having another (bottom) part, egg sack maybe or they fed on something. Somewhere it was written predatory ones could lay 20-30 eggs well obviously I'm more around 100+ |
