Looks like a good buy nice healthy jardini you've got yourself there.
There are pro's and cons for buying private or lfs
Buying private usually means the fish is already feeding and in healthy conditions , it also means any nasty diseases /deformities it could have from the wild or born with have already become apparent that this stage.
Private sellers give fairer prices too if there realistic about the value of the fish.
Shop bought jars are generally juvenile and small which is great if you want to grow one out to get it tame to yourself, but like I've said above that comes with problems.
Some shops will give you a guarantee with fish as long as your water p's are in check and it's of no fault of your own , where as private bought you'd be lucky.
Anyway it seems you made a good choice looking forward to updates on its progression.
