They are difficult. Most will eat pods
only and that`s why you need a very mature tank with plenty of LR
so as to house the pods
. Now if you go to the LFS
and they show you that he is eating prepared foods then you might be OK but I would make the LFS
feed the tank and see for myself that he is eating. Dont take anyones word for it. Most starve to death because they will only eat live pods
and their tank wont produce enough.
