This little hippo tang (about 2.5") had some nasty parasites buried in him. A fresh water dip brought them out wriggling, like thin little slices of a grain of rice, and it was quite traumatizing for him. But he recovered really well! and got really big! I attribute a lot of his recovery to good nutrition, garlic soaked nori is like penicillin for tangs.
This is probably 5-6 months later. He made a complete recovery! These poor little guys sometimes come in terrible condition from some fish stores, but are well worth the effort of looking after.
One of my favourite Gobies, we call this guy David Bowie because of the pink streaks on his face! He was pretty starved when he came from the LFS, he's a fat little sausage now.
