Pbt hmm....there is always chances of ick getting in ur tank.
For pbt first thing is to get one that is eating well n QTed.
Once back home n placed in ur set up,it is most likely to get ick
within days,
Experience tells me to wean it lots of seaweeds soak with garlic
or selcon etc...but must place it in an individual spacious container
n it normally wont resist seaweed as they are algae eater.
Ick will almost always hit ur pbt,but once its stronger n healthier
it will overcome the ICK!
No offence to ALL ...kept 2yrs plus n sold to a reefer here since
its got bigger.
Best of luck to u bro!
