I am planning on incorporating some insect eating plants strategically in the enclosure to handle a gnat issue that appeared from my topsoil/peat substrate. Has anybody tried this yet? I think the success will depend on Blue's desire to smash them lol.....but he does leave the other live plants alone. There are several species that are animal safe, live in tropic conditions, and eat small insects. They also require very low nutrient water, which my RO/DI misting system will provide.
