A week after i got this fish it got this black swollen dot on the stomach. Now 3 weeks later i notice one more. Anything to be concerned about? Fish is not even an inch big.
Typically black spots are Hypermelenization, stings from corals, and mostly harmless, but I have never seen those areas swell.
The spots look to big to be black ich.
Take a good look with a magnifying glass to rule out external parasites.
