I bought my first bamboo shrimp last week and placed him in my 55 gallon community tank. I also had an old filter cartridge in there to keep wet that I was going to be moving to a new filter in a couple days to help seed it.

Well, I haven't moved the cartridge yet because my bamboo shrimp won't leave it alone! He spends a lot of time on the filter floss feasting on all of the little particles stuck to it. I'm thrilled that he's eating so enthusiastically, but is it OK to leave filter floss in there like this for him to feed from? Or should I remove it and let him find his food the way bamboo shrimp normally do?
