Just wanted to see your opinions on this fish…. Curious if you think this is Lympho? Fairly new blue jaw to the system and a few days after adding he grew this little mass on if little dorsal fin…. Thought it was some sort of bacterial infection at first but now it’s kinda smaller in size and growing a couple little lumps in it….. sorry about the crappy pic. He’s still very shy when I walk in the room….
