Hi bro, cheer up.
Not everybody have the same passion like us in the marine hobby. Well, sometimes we go crazy over our passion but to people who dun, they would be thinking it a waste of time. Cite me for example, Im nut about keeping marine but my wife doesnt, she keep telling me she only like to eat fish . Sad , hope she stay away from my fishes. Good thing is she dun bother what i do to my hobby so long i spend enough time with her.
I guess it will take some time and patience for them to understand keeping fish doesnt burn or collapse your house though it will shoot up your utility, haha. It a family afterall, be patience.
