ok,
Max he will get is 2.4 inches.
Needs meat foods like marine fish, crustacean flesh, and shrimp.
He will eat any smaller ornamental shrimp - so be carefull.
It is a aggressive fish, and it will attack similar looking fish,
damsil fish, fire-fish gobies, anthias, gramma's, and juveniles of larger fishes, (e.g., tangs, angelfish, butterflyfish.
This fish is quiet hardy but is prone to color loss. (the magenta strip often fades). Feeding high quality, vitamin enriched food, will help such things from happening.
