Hey guys dilemma had my tank nearly two months now 150g predator tank. Finished cycling added a porcupine puffer he got ich and died after about 5 days. ohh the horror, the feeling of failure any way. I was looking for your opinions on doing a preventative treatment for ich in my main tank with a reef safe product like stop parasite and was looking for your thoughts on that. I just hate to see my new fish get ich it stinks. Lfs told me i should probably add the pufer first heres my line up
im shooting for in my tank.

Porcupine puffer
Green bird wrasse
Humu Humu trigger
miniatius or blue line grouper
niger trigger (Maybe)
