Ok please help me

My house underwent renovation works.
I changed my fish water and didn't do so till 5weeks later
After changing, I realised 3days later, both of my albino bichirs are dying.
My longfin died.I went to quarentine the other one.
After 2days, it recovered.
Then I put it back.
After 2days, I found it dead.

here are some statistics of my tank

-Silver arowana
-2x albino suckers
-2xalbino bichirs


I changed my anti chlorine and increased the salt dosage by a littlebit during the recent change of water.
The other fishes are perfectly fine
I had this bichir since it was young till its abt 6inches now.

I was looking if anyone could tell me how this happened.
Cause its like they're really close to me.
They pretty much were the love of my life when my girl wasent around.
So yeah...What a day
+1 for my long school hours

Sounds like you might have made too big of a WC and changed the parameters too much. It is better to do small changes when you haven't done one for a while. You just have to do multiple small changes to give the fish time to acclamate to the new parameters.

i don't really see the problem as you've described it...

bad luck?

unless something is funny about your tap water, i don't really see what could've went wrong.
