I have just finished trimming my plants and doing a water change. I found something had been munching on my L. Aromatica. I know the Ancistrus will destroy leaves of plants as it tries to collect algae of it but will it actually tear apart stems. It has happened to 2 out the 3 stems. There are some tiny snails, Amano shrimps and a Red Honey Gourami but I don't think it could be those. If it is the Ancistrus is there a reason for him to do this. Is he just not able to find any food in the tank so he resorts to my wonderfully growing stems??
