I have a 54 corner planted tank. In the last three days, I have lost seven fish. The first five were all pelvicachromis taeniatus 'moliwe. The most recent two were a congo tetra and a torpedo barb. All fish look healthy and feed as normal. Coloration is normal. No damage to fins or body. Water parameters are stable and have been the same for over a year now. Plants are doing well. I treated with prazipro two days ago, thinking it was some sort of internal parasite. While the pelvicachromis have been in the tank for some time, the tetras and barbs are recent additions. Anyone have any advice as to additional treatments? Suggestions as to what it is that is killing my fish?

Yesterday, I did a 50% change on the tank. I added Hex-out to the water. I have since decided that it must be an external parasite that I can't see. This morning I added quick-cure to the tank. This evening I will place a sterilizer on the tank in hopes that this will help.
I think the Hex-out is a bad idea. There is very low likely-hood of it being an external parasite if you do not see anything. It is more likely to be something in the water, unless the new fish were carrying a virus. This sort of die-off suggests water problems to me. Are you adding CO2?
My first thought was water problems as well. Though the tank has been stable for well over a year now. I do the same routine on it since first setting it up. A 50% change weekly with RO water is standard. I use the hagen master test kit to monitor all the parameters before and 24 hours after doing a water change, or as needed.
Yes I am injecting co2, but the levels are well within acceptable range based on Ph and lighting. The co2 goes off at night and additional airation/filtration comes on just in case the co2 levels would cause a problem during the night.
I agree that metronidozol was a mistake in that it does not seem to be internal. I am leaning toward gill flukes. This would explain the normal activity level/feeding and then gasping/death as well as the fact that there are no visible symptoms (other than the heavy breathing which comes on hours before death).
