I help out my good friend David Lo at Nano Tanks Australia on Saturdays. I'm not a paid employee, but Dave is one of my best friends and I quite enjoy being around his beautiful fish. In fact, I'm learning very slowly about acquarium fish, mainly Betta splendens, but a variety of other fish. His partner Kelvin who owns OZ Discus deals with high-quality Discus, which I sometimes assist with.
I am disclosing this in the name of transparency and to avoid any perceived conflict of interest.
