Sorry to hear about your issues Josh
There's definitely something not right in your tank. That monti cap should be bullet proof! I wouldn't worry too much about the confusa. I've never had major polyp extension out of them but they still thrive.
I don't know much about the frogskin acro. I don't think I've ever had one. Stags can be touchy.
Anyway, swing by and grab some bullet proof red/orange digi and yellow/green birdsnest. I can't seem to kill that stuff!
