i've noticed this lump on my gar about 2 months ago. it has gotten slightley larger. Can fish get tumors or cysts? It doesn't seem to have affected the fish. Still active. Still eating. Any feedback would be great.
to ansewr your questions directly. Yes. but what is causing it? can you take a GOOD picture? Use your macro option (flower) and make sure it's focused. I focus then move in and out from the tank to get it crisp. also it helps if you focus on something solid like gravel.
