Rasbora red lump

[cornelius85]

Hi there is a red lump on my rasbora  it looks like a wound.

Any idea what this is. This fish is not eating since yesterday, and kinda breathing heavily. 

Last night that lump was not there.

 

• pH=7.0
• Nitrates=20
• Hardness between 7-14
• Nitrite=0
• Ammonia=0
• KH/Buffer=10
• Water Temperature =77 F (25C)

Edit: Thought it was not eating but it went crazy for o-nip tabs with the rest of the tank. 

Edit 2 Seperated it tıo quarantine. Waiting for further instructions

Is there anyway to get a little bit more clear of a picture in the QT tank? I can't quite tell on this picture. Where on the body is it located?

@BNye maybe this would help. I circled it.

@cornelius85 That is helpful thanks. What other fish are in the tank? And it is a lump correct not like a open sore like a hole in the skin?

[cornelius85]

@BNye There are cardinal tetras and panda corys. And no it is not  like an open wound or a hole, it is  under the skin  more like an internal bleeding. When you look at to the fish from top or front/back it is visible, so yes it is a lump.

I have some news.

Yesterday After putting this fist in to quarantine tank. I applied sera baktopur and tropical sanital ketapang salt.

This morning the lump was gone there was a little scar left in its place. Also fish is doing much better.

Sera baktopur has a 3 day medication period. Will see what happens in the third day.

 

I still want to kow what this is.
