Well the bad thing of having so many plants is you don't look so hard for fish, assuming they are in there somewhere.
I just thawed a bloodworm cube, and dropped it into the tank. Normally the female pink in first on scene. Not seeing her I looked for her. Not finding her I think is she stuck under the rock...I look under the tank and sure enough I she just a bit of her all buried in rocks. Quickly I move the rock away and she slowly swims out all beat up swimming sideways...
Not looking good at all
