fin rot or nipping on my colombian tetras?
This morning I just noticed something that looks like it might be fin rot on the tips of a couple of my Colombian Tetras tails, also one spot on the tip of a dorsal fin. The areas affected are very small, pale - almost white - and not at all cottony or raised. If it is fin rot, I'm really puzzled because I take good care of the water.
My water perimeters are: A=0, Trites=0, Trates less than 20. I do 35% - 50% W/C weekly and keep my filters clean and vacuum the substrate regularly. filtration: Aquean HOB 30, Aquaclear HOB 50
I've had these Colombians for several months - healthy, happy, eat well. A couple of weeks ago, though, I added 6 serpea tetras (after quarantine). The serpeas look great, no tail or finnage issues.
What do you think? Do I suspect fin rot on the Colombians or is it possible the serpeas might be nipping? I'm not seeing it happening - the tank appears really harmonious (yes, even with the 3 dwarf gouramis which have been in there forever).
Should I treat the tank for fin rot just as a precaution?
Or is it more likely the serpeas might be causing the trouble?
I tried to snap a photo - but those tetras will not cooperate.
