its the only thing wrong with him. its kinda like around the fin area. i kinda ran out of funds and i dont have an atm card or anything yet, so i cant really buy anything.
well its very rare to get a pure black molly mine was orange near the bottom and also had some white on the fin. so its either just developing colour but is it eating right swimming right?
would you be able to get a pic? if it looks fluffy or like wool it could be fungus but thats not nomally in spots . ich are white spots.
