If you can get a photo of the bugs, post it to the Dr. Ron forum at RC. He's great at IDing bugs.
We found some strange looking bugs in our 72g. Turns out they are good isopods, so we aren't worried about them now. While I was researching parasitic isopods, I was told that the tank would have to remain without fish for at least six months, maybe more, to eradicate parasitic isopods
That meant no feeding the tank, either, because they will subsist on anything, even detritus, until fish come along. Man, they're evil
