Hi guys, I've had my tiger barbs for over a year without any issues, I bought them when they were small, and had them in a 20 G tank. About 6 months ago I moved them to a brand new 70 G tank.

Needless to say the tank was properly cycled and all.

The fish were properly quarantined, and I haven't added any new fish in more or less 4 months.


since a month or so, I have noticed my checkered, gold and tiger barbs started to look thin, despite being well fed.

Some people told me they might be parasites, so I deparasited them with metronidazol, and later, with a product used for that purpose for dogs.

Nothing.

I have 2 peral gouramis, 8 harlequins, 4 boesemani rainbowfish as well, that seem unaffected.

I have already lost 4 gold barbs, 3 checkered barbs and 1 tiger barb. But about 4 more tiger barbs seem affected.

I thought it was fish TB but there is no bent spine, and they eat fine...

It only affects barbs... this is what they look like.

Do they deliver white excrements? If not, it should not be Hexamita, so not necessarily vulnerable to metronidazol. I would try something as Sera Nematol.
