Looks great. Do you have a picture of your tank so we can see where the traps are placed?
PS Don't worry. Your English is great. Just curious, but is your native tongue French?

Here is a small description of my tank.
Tank of 220 Gallons with sump of 90 Gallons.
Skimmer Euro-Reef RS8-3+.
Calcium reactor Deltec PF-600.
Tunze Multicontroller 7095 with 2 stream 6100 and wave box.
Neptune AquaController Junior (DC8).
3 MH XM of 250W 20K and 2 VHO super actinic.
RO/DI and top off, pinpoint monitor etc...
Here is the picutres of the tank with the traps.

The Isopod that is pictured appears to be a Sphaeromatidae Isopod. I have many of these little guys in my 180 and they do no harm to your fish. I initially got freaked out when I saw them, however after alot of research and close identification and comparison, I was relieved that these guys would not be chowing down on my fish. The reproduction of these little guys seems to go in cycles, and I currently have 20-30 of them in my filter sock everytime I change it, and then other times I may have only 1-2 specimens. Check out this article http://www.reefkeeping.com/issues/2002-05/rs/index.php
Hope this helps.

It is a possibility what he is catching is Sphaeromatidae, but I believe he said earlier that they cannot roll up into a complete ball when alive, so that would eliminate Sphaeromatidae as a possibility. If he can redo that test on the next few he captures then he can be sure. They do look more like Cirolanids to me than Sphaeromatidae.

skimmer,
I have to agree, great job on the journaling of the captures. I'm going to link to this thread from my author forum. Keep up the updates!

Skimmer2 stated "I forgot, they do not seem to be afraid of the light of the flashlight."
So you are able to see them on the glass when the lights are on? If so, this is not typical of the cirolanid. It is typical of the Sphaeromatidae. The ones I have attach to any algae that may be on the glass. They are there even when my MHs are on. I had the same in my old tank my my six-line wrasse wiped out most of the population. In addition, I am still not convinced that these are cirolanids based on the pics that Skimmer2 posted. Take note that the eyes of the isopod are smaller and spread farther apart. Cirolanids have larger eyes that sit closer together and are positioned higher on the front of the body. It looks like there isn't any fish in the tank yet, so you won't know for certain if they are attached to the specimen after the lights go out. Definately think about purchasing a red light from the sporting good section.
IMO it is nothing to be stressed about. Good luck with the tank, I like the stand and canopy design.

Jack, I must give you reason partly.
Effectively, I'm not convinced that it's cirolanids but I'm not convinced that it's Sphaeromatidae also.
The other peoples who bought live rock of the same arrival, do not report aggression of cirolanid.
I saw some only when the vho is on, but not when the MHs is on.
In the doubt, I like better to prevent that to cure. What do you think?
