My bamboo shrimp has been in the built in filter on the back of my tank for about 2 weeks now. He is underneath some bio-balls, that are underneath a drip tray. That compartment fills up with water, so he IS completely submerged in about 10 inches of water, with a bunch of bio-balls to swim around and through. I attempted to take apart the filter, take out all the filter media, and catch him in a net. After about 30 minutes I gave up and put the filter back together. I know this is probably tough to picture, but I really just want to know if he can live back there? Hey seems fine every time I look, but I'm a little worried about this set up long term lol.
