Fishes keeps dying but invertebrates are fine

What did the respiration rate of the fish look like? Any odd behavior?
You usually won’t see any spots with velvet, just swimming into flow and rapid breathing before death.
Respiration rate looks good in first 3 days and then 4th day onwards it'll increase with occasional swims to the top of water. So odd behaviour only on 4th day
 
If the angel had ich and you only waited a week I'd start there tbh . Go fishless for the recommended time and try again
 
did you add any sort of bacterial starter or did you use mature rock or bio media?
I'm using a local product. Although not at all sure about it's efficacy

Yeah I will take a gap before adding any new fish. Give it some time atleast. Suffered some great losses!!

if at all possible, see if you can get a bit of mature rock from a clean and well established system, whether it be a local hobbyist or reputable LFS. You'll be glad you did, biofilter maturity and diversity is key to long term success

I doubt it's ammonia if the tank has been cycled. I'd wait the recommended amount of days then try a small fish like a clown fish . Don't add nothing big it's a small tank
 
In this video, does the surface agitation looks good enough or I need more. I'm asking twice as for my small system, AC powerhead will create very strong flows

Sure. I'll try to do this thing along with getting my ammonia checked.

Sounds good. I'll keep just a clownfish maybe. Give it some time before I do that. I tried methods like 90% water change, putting one pellet a day, etc but still couldn't keep a single fish for more than 6 days, over a time of 3-4 weeks. So lastly I am almost on the verge of giving up as to why my fishes keeps dying

Don't give up you just got to be patient and wait it out for a few weeks before adding fish . Don't add any chemicals in the meantime . Just make sure to feed the shrimp every few days .
 
Best to wait at least 60 days before a new fish is put in and to quarantine + treat new additions.
We may not know what killed them, but can at least all possible variables can be eliminated.

Yeah. Patience is the key I guess.
I won't add any chemicals okay.
There are no shrimps,
I've two star, one slug and porcelain crab as inverts. They've been since almost 2 months now.

Right. Gotta be patient with adding fishes!
 
Your aquriam is to small and to new/ clean to house such a big fish/ speices. I doubt diesese is an issue, I think main cause of death is the size of your aquarium and fish you have tried to introduce. you may of introduced diesese but in my honest opinion your aquarium is to small for survival of the fish you want/ attempting to keep.
Like keeping a whale in a swimming pool...

Could be.. 10 gallons sounds ridiculously small TBH. Hence I am thinking it's the tanks' bioload which could be the problem. I guess it's not able to process the ammonia from fish, but from inverts? I don't know that
