I have a couple asian ambula plants in my tank and each morning I wake up or throughout the day it gets magically clipped. I have a red clawed crab, iridescent shark, columbian catfish shark, khuli loach and some danios. Who's responsible for clipping the plant all the time. I scoop out the floating clipping and then couple hours later another is clipped? Could it be the snails? Are the fish even responsible?
