Yes, giant gouramies also like to eat plants. Here in my country Indonesia, farmers often feed their giant gouramies with the leaves of taro or giant elephant ear plant (Alocasia macrorrhizos) which is a type of Aroid jut like pothos. The leaves contain calcium oxalate crystals that can be extremely irritating to human skin, but fishes munch on them with no issue at all.
My silver dollars are a little weird, but I have successfully had Peace Lilies grow out of their tank before. They left the roots alone. They are a bit of an exception though, because they also think Swords are gross and I can grow it in their tank as well.
@@Riffwaters I also wanted to say I love your fire eel, I've always wanted one since I saw one on a poster 20 years ago, living in Australia it is extremely hard to get fish like that, I finally got my hands on 1 a month ago for a pretty penny ( they sell anywhere from $500- over $1000AUD) he is only a baby and is my favorite out of my fish, I just love watching your videos on your big guy and hope one day he gets as big as yours, cheers
