This Japanese boy Ryo Watanabe is currently based in Japan, but used to be in Singapore for some time (his mother works here). I think he is probably back in Singapore recently again based on his videos.
Very amazing discus fish store tour. I usually enjoy watching his videos during meals, I think I have watched almost every single video (except those super long video interviews which may be more than an hour).
Do subscribe to his channel, and like, share, etc. His videos are usually very professionally produced, and he speaks very good English. Sometimes, I wish I have the time to tour all the fish stores like him.
SG Bearded Aquarist Fish Videos
Another fish YouTuber based in SG is SG Bearded Aquarist. Currently, he seems to be “inactive” for quite some time, maybe working on a new project? His videos are also very professionally produced, and he does branch out to overseas aquariums/ saltwater/ planted tanks as well.
One of my favorite videos from SG Bearded Aquarist is the one below (featuring Zaric and Jarenn Foo who are expert Pleco breeders).

Discus is the high-class aquarium fish, very pretty, expensive.
You can start with cheaper baby discus of average species, $18 each, size of 20-cent coin.
Discus is chiclid (like angel fish) , territorial can not co-exist with other smaller fish, will chase or kill them.
