after doing a few water changes, i noticed that my new fish, laetacara dorsigera, have a few black marks on their ventral and anal fins, as well as one or two on their bodies. i suspect it is chlorine burn as it only appeared after the 3 water changes i did using the python. any confirmation that this may be the case? here's a video of the two. ammonia/nitrite are both 0.
when i refill the tank with the python, do i add dechlor before every 2 gallons, or after every 2 gallons? do chlorine burns heal with time or is the damage permanent?
