if they recover I would still give it a try. On the other hand I doubt that any wholesaler would treat the fish the right way, they are most likely kept in tap water and without adjusting the environment to their needs I do not think they have much of a chance. I have no idea why people in trade always try to harden such kind of fish and I have the same experience with South American species too. traders put them 8° DGH water, pH 7-8 and than wonder why they are dying. RO for those couple of tanks with these fish would cost them close to nothing and only a little effort. Of course I do not mean to offend anyone in Ruinemans if they are different. I know from my own experience, that from the epidemiological point of view it is very hard to limit all the transition vectors but I beleave that species from very acid black waters are very well protected by simulating their environment well.
