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...
Well it looks like she is going to pull thru. At the moment her tail is nearly all gone. Her right eye may be lost, but she swimming normally and eating.
