$5 gotten it from SeaLife.
This goby is very very prone to whitespot initially during acclimatization.
Now it's become itch resistant.
But recently I added a 2nd one..kenna bully by the existing one..now it has itch too. Trying to get it to recover by garlic everyday. It has itch for about 2 weeks already.
Other fish are unaffected. They have resistance.
