My 2 year + HM lost most of its colors di. Any idea why?

It seems healthy enough, eating well, bubble nest, active and all.

hi guys wanna ask, new betta owner here. i have a few qs..

1) what does it mean if my betta swims with his fins close to his body? sorry i dont know what type of betta he is. i just got him 12 days ago. previously he looks really beautiful swimming with all his tail and fins opened up in the fish shop, but now it seems closed. was wondering is this a sign of stress or sickness.

2) he recently has a problem floating properly, he swims vertically and that really scares me. i read up and think he has swim bladder disease. is this dangerous? will he recover from this and usually how long will he be normal again? previously i fed him with bettaX pellets from the pet shop: i followed the instruction of 7 pellets, twice daily...however i read up and saw people recommending to only feed 2-3 pellet twice a day. Am i overfeeding him? and why would the betta pellet instruction says to give 7 huhu.. i'm worried that i might kill him

3) i recently bought a larger tank for him, an upgrade from a small jar, however he doesnt seem to really like it. he only stays in the upper right and left corner and sometimes darts back and forth. he doesnt seem to explore his tank. why is that?

4) i was thinking of incorporating dried bloodworms flakes to his diet, how frequent should i feed him these?

sorry for the many qs, just worried for my betta - he doesnt seem too active and happy

Hi junyang96 victorsoo

Thank you both for your replies. I really appreciate it so much that you both took the time to explain to a newbie like me.

Unfortunately,  my Fighter died this morning

3 days ago, i saw something that look like white specks at his belly area. I thought it was fungus. I then proceeded to order some ketapang leaves in hope that this will cure him. Also i thought it would be better for the water condition. Btw, i have just a basic aquarium 5litres capacity.  No filter, no thermostat,  no plants. Only a wood and some gravel as i have just started to buy him last 2 weeks ago. I did not have a cycled tank as i didnt know what that was. I used normal tap water and add antichlorine and let it rest for half an hour before changing. I do daily water change about 50%. I thought my water looked pretty clean because of the daily change.

It was not until late last night i wanted to take a closer look at the white patch and proceeded to take a photo of him with flash. To my horror, i saw that he had gold specks on his face and body instead of white specks. It was truly difficult to see with the naked eye unless u shine a torch or take a flash photograph of him. I quickly googled and found out he has Velvet disease aka gold rust disease. That explains why he was swimming with his fins closed, low mood, swims funny: always darting back and forth, and had poor appetite. Also i saw just yesterday his fins was starting to rot. As he swam around, i saw a chunk of his fin fell out T___T
Does this mean he has velvet and fin rot together? T______T

I tried to find meds to cure velvet but couldn't so i planned to go search some from LFS. However it was too late.

I was wondering though:

1) is my water change routine ok? Am i doing anything wrong? I don't have a thermostat but i thought room temp water was fine, no? >.<

2) since velvet is caused by parasites, does this mean normal tap water has them? where does it come from? Or did the shop sell me a sick betta? He looked fine to me when i bought him though

3) where do i find velvet disease meds here in kl? I saw that malachite green or copper sulfate is good but i dont see anyone selling here online. Maybe anyone can give me the names and location to buy some?

4) can a betta have 2 coexisting diseases together,  eg: fin rot and betta. If so, can we mix both meds together and pour in the tank? Or will it kill the fish faster.

5) instead of aquarium salt, can i use table salt. And how much to add to 2.5L of water?

Sorry for my lengthy post and many questions. I just wanted to let new owners know that velvet is fatal and often missed by amateurs like me. So use a torch to check your betta frequently huhu. Looking forward to hearing some thoughts from u guys out there. I'll attach some before and after pics below. Could you guys tell me did he have fin rot when i bought him?

Bought a new betta dumbo ear type. He's the total opposite of the first one. Really active and seems happy exploring his tank. I checked with torch light to look for gold rust which luckily i didn't find any. I did water change as the same and added indian almond leaves. I think he seems to like it. Came home one day and saw that he made a bubble nest 😁 Now I'm currently feeding him some bloodworm flakes and pellets, however the flakes does leave an oily residue at the surface of the water and my tank does not have a filter. Was wondering are the flakes recommended? It says it contains some salmon oil

Got a (i dunno-what-type-is-it) betta and placed it in a semi planted tank; sharing with couple of tetras and miniature algae eaters. So far it is doing well. The betta really hates shrimps tho.

Thanks victorsoo
He's really quite happy and active ahaha
Alright I'll continue giving him the flakes..
You didn't get a betta yourself?

Super in love wit this .. trying to search around

Aww such a cute one victorsoo

I'll try Hikari pellets once my current stash finishes

Btw does anyone knows where i can get a good marimo?
