just got some mobas last week. They're 1 inch and bigger. did a water change 4 days ago, then notice some flashing. several of them seem to be breathing faster than others. They all eat like pigs. No white spots on their bodies. Do frontosa juvies at 1 inch appear to breath fast, compared to other cichlids? What could cause fish to flash 4 days after a water change? Checked my parameters. pH 8, nitrites none, nitrates 20. Seems to be more flashing after I feed. Is there a slight ammonia spike due to the feeding?
