Synodontis angelicus growth??

[TheMoneyTank(TMT)]

Brought a 2 inch angelicus for. £24.95 looks legit wondering what growth I can expect

Moderate. AFAIK and IME, these usually do not exceed a foot even after many years but most likely will stay around 8"-10" mark, which will be reached over about 2-3 year period.
