I have an inkling that my Pleco in my moderately planted tank is eating one of my plants. I feed him/her Aquarian Algae chips usually every night. However I believe I forgot last night and this afternoon I noticed a plant missing its leafs. I'm upset because I have never had ANY luck with plants and this time I bought plant food/fertilizer, etc and now one of my recently purchased plants is missing all but two of its limbs. Any suggestions are appreciated.
