Maybe a Butter Bream? ???
There are 2 varieties that I know of, one spotted and the other striped. Both give you a very nasty sting if they spike you. Basically it burns like heck... They can grow to be a fair size, biggest I've seen was over 35 cm
As with most of such stings the treatment is to immerse in water as hot as you can bear asap
I tend to get them in the cast net at times, a good one to keep your eye on....
