It is a type of plastic however it is biodegradable and does not give off any gases
The engines give off some gases, but that has been considerably reduced.
Plants give off oxygen during photosynthesis and carbon dioxide during respiration.
i recommend that you have a filtration system in the bowl as during the day plants will give off oxygen while it photosynthasises but at night it gives off gasses and the fish needs to the oxygen to breath. the plant will not be enough for the fish and if you do not have the room for a basic filtration system then the bowl is to small for the fish
