Hi guys, I was wondering if someone has any advice. I have a 36 gallon with 1 betta, 12 neons, 5 pygmy cory's, 2 Myers hillstream loaches and 3 assassin snails plus pest snails that are slowly going away. Something keeps digging up any plant I put into one particular corner. They'll leave the other plants alone but for some reason my fish don't want plants in that corner. Any advice?
