I am not sure what kinda wild betta , probably midas or akarensis.
The wild betta is very shy, the plakat is used to be very aggressive when he was by himself. Now they both live together peacefully.
Nice looking wild. Not midas but could be akarensis. How big is your tank and what temperature do you have the water? The one major issue with keeping domestic betts (your plakat) and wild species together is water temperature since wild bettas tend to like cooler water temps(low to mid 70's F) and domestics prefer and do better in warmer water (78F min).
Oh, wow, they are both so beautiful! I've never seen wild ones being sold around here, that is the one fish I would be very, very, extremely, tempted to start a third tank!!!!
