Hi. I want to ask for advice and help. I have a tiger barb that is still 4 cm long. I have kept him since 3 months ago. 2 weeks ago, he became sedentary and now he got what looks like a wound that is located at the bottom part of the body or should i say the belly. The wound color is red and it look like it is located inside rhe body since no slim or tissue or whatsoever dangling from his skin.His swimming capability become quite lousy compare to other barb although it is another story when it comes to the feeding time. I keep him with 4 other barb. What kind of medicine should i give him? Thanks
