If you went back 60 years ago, it would've been virtually impossible to keep saltwater fish in your own home.

Saltwater fish keeping, in reality, in the hobby, has only been in existence for about 40 to 50 years maximum, and even then, it was an incredibly difficult and challenging section of the hobby to get into.

Most people who used to keep fr-- saltwater never really had that much success with it.





So the likes of fish that comes from tropical oceans, from the Caribbean, to the Red Sea, to Southeast Asia, to Australia.


When I used to work in the hobby, especially towards the end of the noughties, I used to be asked this all the time, "I would like to keep Dory and I would like to keep a Nemo." Nine out of 10 times, it wouldn't happen.

So the people would come in expecting to just pick up a, an aquarium and keep those two fish, and it's not so straightforward.


Dory, the regal tang, are one of the most difficult fish to look after and require incredibly large aquariums and a lot of work to go in, even though they are relatively quite easy to look after in the sense that they are relatively easy to find, easy in terms of affordability, but they do come with caveats that they need larger aquariums.

And w- what I've noticed in this hobby is you either camp tropical freshwater or you camp tropical saltwater.

It's a bit like a footballer being right-footed and left-footed, or you can write with your right hand and write with your left hand at the same time, because they, they all require a different style of fish keeping.


I mean, it, it's a lot harder than that for the main reason that it's not water coming out of your tap.
