Bought 10 fivebanded barbs and one disappeared

Okay so, I bought for my 31 gallon community tank 10 Desmopuntius pentazona. They Are some amazing fish, I think they're a lot of fun. BUUUUT one of them disappeared today. I found like a spine with some ribs and some fins still attached to the corpse, and I know that even if the fish died the Siamese algae eaters eat it, but who killed it? i had to do a ich treatment, maybe it's because of it or because of one of the tank mates iyo?
Just in case you wanted to see them

Without knowing more details, pinpointing the cause of death after the event is guesswork. Could have been killed by a tankmate, could have already been in poor health when you bought it.

I see, it's just that it surprises me. Maybe the ich has made him (yeah it was one of the males) more and more weak. I have honey Gouramis in there and they tend to be a little predatory at times

My guess is it just died and became a meal for the other fish.
