The dark blue spots are always there. Yeah he's a smaller one probably about 2 1/2 inches or just above. and i haven't tried the garlic yet i will have to try that out for sure!
My tang has been starting to get dark blue spots on both sides of him. He keeps rubbing against the rocks like he is scratching at it. I don't have a clue what it is if anyone has any ideas. I'm all ears!
