This is a notorious issue with rnt’s. I always loose at least one from each new batch.

One thing you didn’t mention is your temperature, what are you keeping the tank at? They like it a little warmer than what most sites / info says , like 27/28c.

As you know they are schoolers and will feel safer in a bigger group but a week shouldn’t affect them too much. Reduce stress and keeps lights dimmed or off where possible . Try and reduce foot traffic if possible around the tank too.

Personally if it were me I’d start looking for another healthy group from another vendor, if they don’t look healthy , don’t bother. They are sensitive little fish and in my experience don’t handle transitions well, if you do get more consider a slower acclimation , I found it helped a lot ! The newer group I got have a pretty green spot on the head and they have been a lot more robust.

They are glorious when they school tightly ! You won’t regret sourcing more

My fingers are crossed for the little guy .

You’re Definitely not an exterminator !! I’ve mentioned I’ve lost some out of every batch and honestly I think it’s an acclimation / temperature thing, plus then just being so sensitive to change. Don’t blame yourself.

Everything you read online says 25c is good for them but it isn’t ! There’s a reason discus/ ram keepers have rummy’s too. They really do need that couple of degrees warmer to stop issues. So even if you acclimate well and they settle , a few months later down the line at that lower temp you’ll likely start to see some issues and lose a few more. It’s an all too common story.

I’m seriously rooting for the little guy . If you can find healthy , robust rnt then get them. Diamond back are even better if you can find them

Oh no, poor little guy. One of the batches I had I left to grow out in the shop for a couple of months and just kept checking in to make sure they still had them and they were the same ones.

Im sure the qt will make the next ones more
Comfortable. Good luck with them !
