Illness & Symptoms

In a few words, can you explain the symptoms?
red scratches on both sides of the tiger barbs body
Have you started any treatment for the illness?
Was your fish physically ill or injured upon purchase? No just very stressed
How has its behavior and appearance changed, if at all? Apart from the red scratches his behavior seems to be normal. The other barbs nip at him but that’s what tiger barbs do. He does seem to be a little more stressed out over the last day. Pictures are attached.

I hope this is enough information, I am new to the hobby and want to make the best decision for the care of my poor little barb.


IMO, the flank hemorrhaging on the male Tiger Barb is likely due to fighting. Likely scraped himself on decor. As long as the Barb is eating and otherwise acting normally, probably no worries. Tiger Barbs are pretty durable.

He looks worse this morning, any advise?


Hemorrhaging isn't always caused by an abrasion, sometimes its Septicemia, a symptom of an internal bacterial or even viral infection.
That would be the worst case scenario, and really nothing could be done to save the Barb.
As already mentioned, if he is eating & swimming normally, clean water, good nutrition & time should heal him up.
