Hi there, I'm from Hong Kong.
I have been keeping coral fishes for years, and recently I have bought a
new home for my old fishes, but I also lost several fishes because of the
change... Crying or Very sad

Let's share a short video of my tank : http://youtu.be/2JjLHOztUsY

Hello and welcome to the forum.
Thank you for posting the video. I see you have several potentially very large Angelfish in there and some aggression issues; what size tank is that and how long has it been set up?

Yes, there are some potentially large angelfish, and of course they fight
each other sometimes. It happens not only among large angelfishes, but
also small angelfishes, but not serious.

My main tank size is 140X60X60cm and the sump size is 82X32X45cm.
The total water volumn is about 620L. This is the bigger tank I can put
in my house. Those big fishes have been with me for 3-4 years.

They were about 10cm or smaller when I bought them years ago...they
are getting bigger and bigger, that's one of the reasons why I have to
buy them a new home.

That is seriously overcrowded tank with some already stunted fish.

Please revise your working volume as the overall outer measurements give a gross volume of 622 litres. You need to allow for glass & media & decor ( & fish) to get water volume.

There should be about 40 litres of glass alone in the main tank.

How is it an unfair statement?
The fish are far smaller than would be expected in the wild or in a more suitable tank.

You have to take some of the blame for buying too many fish and fish that grow too large for you to accommodate. Certainly after the first few you must have realised there was better information than just the store trying to sell things.

Your options are splitting the fish between several tanks - even if these tanks are not yours - or getting a larger tank but as there will be territory clashed some of the fish need splitting anyway.

Which is better or worse? Giving fish away to a good home or having them die early?

As I said, they were very small when I bought those fishes, and I did not
know how big they could be, and of course, I cannot ask them to stop
growing after I took them home. Therefore, I have been doing my best
to provide best environment to my fishes, like changing water every week,
changing better equipments and so on.

You are correct my friend; you cannot ask them to stop growing.
Many aquarists find themselves at some point with an over crowded system; they grow fast when they are smaller, but eventually they will become unhappy and decline in health due to confinement stress, bullying, lack of territory, etc. I have been in this situation myself and sometimes it sneaks up on you over a long period of time.

Now, some of the fishes are still getting bigger and bigger, and I cannot afford changing tank anymore. What am I suppose to do? Releasing all
those fishes to the dirty sea in Hong Kong? Or give them to someone who has a huge tank?


Releasing into local waters, no. One suggestion is to contact a local public aquarium (Ocean Park?) or perhaps another display and talk to them about adopting your larger specimens. It's not that we want to offend you; in reality we are mainly concerned with the overall health of your system and the animals themselves. Several of the large specimens you have selected are very territorial in nature. Please understand, in the wild a single adult male marine Angelfish can easily have a territory in excess of 10,000 square feet.
