I recently started up a 33 gallon tank and transferred everything from a existing 29 gallon. The 29 only had 5 apistogrammas in it. I added 6 black neon tetras to the new tank and everything seems good. I noticed the black neon tetras had very small white spots on their fins. The apistogrammas dont yet have any of the spots on them and all the fish are swimming fine and seem happy. Just want know if i should start the salt treatment.
