I've got loads of isopods that look similar in my tank. They come out of hiding when I feed things after lights out and always swoop down on food. I've had fish in with them for about 6 weeks so far with no trouble yet. Like yours the eyes are quite small. Given that they eat anything I feed the tank I came to the conclusion that it is unlikely that they are obligate fish parasites.
I don't know, but CirolanidHunter suggest waiting between 60 and 90 days.<a href=showthread.php?s=&postid=7551058#post7551058 target=_blank>Originally posted</a> by Travis L. Stevens
So far so good. Personally, how long would it take for nothing to show up before you would believe that they are all gone?
