I’m not sure if that’s velvet I think not

 

[RainGamma]

Isn’t velvet pretty fast at killing? I don’t think it would be velvet right

 

[RainGamma]

I’m pretty sure my Cory only does it when he is scared (my Corys run when I come up to them) I could test that out as They are scared of humans I guess. But I think it’s not velvet

 

[RainGamma]

That’s my betta btw, nothing looks wrong with him

 

[RainGamma]

Some people say “lack of light” could cure velvet? Is that true? I know Corys can still hunt at night so. Plus velvet need light to survive. Just for a safety precaution I might leave my lights off for like 3 days and do 70% water changes. Even ways I’ve been waiting 20 minutes in the dark for my Cory to twitch and nothing is happening. I’m gonna keep waiting. (what do you guys think of that)

 

[RainGamma]

it looks like my betta has velvet but I might be wrong.. (I don’t see anything out of the ordinary happening to my betta)

Maybe I’m wrong but he kinda has a brownish color under his uhh (head I guess idk) maybe it’s nothing bec nothing seems wrong with him

The Corydoras and Betta do not appear to have Velvet.

Velvet is an external protozoan parasite and can live in dark or light tanks. Once it is on the fish it simply feeds off the blood from the fish.

Medications that contain Copper Sulfate or Malachite Green will kill external protozoan parasites like velvet, but they are also quite toxic. The safest method of treating velvet and white spot is with heat. Raise the water temperature to 30C (86F) and keep the temperature there for 2 weeks. You can add a bit of salt if you like but it isn't normally needed.

What is your ammonia level? Nitrite is too high which might be cause the cory to twitch.. do a 50% water until nitrite levels are lowered to 0 and from there do daily 50% water changes (half of your tank) until your nitrite levels are 0ppm for 7 continous days.

My little one is doing it too (one I bought and put in tank). there doesn’t seem anything wrong with it. It does it did It when it was searching for food.

 

[RainGamma]

Idk what the problem is but I did a water change and it went back to normal.

^ I saw this video not sure if that’s what my fish has

 

[RainGamma]

I feel like nothing is wrong but I will keep looking, I don’t see any signs of anything.

@Salty&Onion @Colin_T

one of my Corys lost their barrels not sure when but it must Be recent

 

[Salty&Onion]

Do I see a betta in the background? It could happen that the betta has attacked the cory. What is the substrate? It looks too rough for cories, they need sand.
