What are the ammonia levels at? also, what else are you keeping with them in the tank?

tested the amonia straight after the death and it was at 0.10 (very minimal)
I am probably overstocked, but i dont think thats its caused the problem.
I have a rainbow shark but he only chases the loaches, so i doubt he killed the tetra.
I did however do something very silly about 10 days ago.. My filter was running slow, so I opened it up and the pads were heavily clogged, so i squeezed them both in a bucket of tap water and removed about 80 % of the good bacteria... Have been checking the levels every few days since and doing water changes every week (50%), and the usual tests would show before and after water changed
Ph 7.4
Amonia 0.10
Nitrite 0
Nitrate 5-10.

You are REALLY overstocked. It may be a bacteriAl issue though or aggression from a bottom dweller based on wound location

Yes, am getting juwel rio 400 delivered on Wednesday, so the overstocking wont be an issue after that.
I dont really see the botton dwellers going up to the top level where the tetras are always swimming, so i doubt that.

Are u saying it looks like a wound caused by another fish ?
