looks like it has a ‘scorpion’ tail. If it is a naga / scorpion / ghost type chilli then my advice would be to do a taste test with a cocktail stick. Push the stik in the chilli, twirl around a little- place stick on tongue, if brave suck stick. If it feels like you have just put a soldering iron in your mouth then it is indeed a hot chilli. You will then start to drool uncontrollably. If very brave then cut a roundel and have a proper chew. Or for an interesting experiment just pop a whole one in and get ready for pain.
My chillies were a complete disaster this year as I experimented with growing media (and learnt that 100% perlite on top of a little gravel is useless).
Last year I grew: carolina reapers, naga bhut jalokas, lemon aji, zimbawean black, trinidad moruga, yellow 7 pot, red 7 pot, chocolate moruga, cayenne and some other chillies I can’t recall which.
The hot chillies were indeed really hot. I turned most of them into chilli sauce- which is now very hot indeed.
For the record in comparison to Naga / scorpion type chillies Habeneros are not hot.
Chillies derive their ‘hot’ sensation from capsaicin which directly stimulates the pain receptors in your trigeminal (and other) nerves that provide sensory innervation to the mouth (for example there is often a bit of vagus nerve innervation- which probably explains why my ears (or parts of my ears) also hurt when I eat hot chillies)- rather than stimulating your taste buds as well as some people developing uncontrollable hiccuping (as well as crying, runny nose, drooling).
Have fun and tell us what happens.
