Shes not interested in the mirror, must be a bloke then! , however the other girls were. Maybe shes to sick to care. She has very long pectoral fins as well and no visible egg spot, the only reason she is still in there is she is no trouble and gets on fine with the other girls. Here is another picture and one of the dead crown tail. Bloat? you only get that if you eat, weedy and interbred more like, whats wrong with the human race? This fish was never meant to be and now she has infected my girls with who knows what ! Thankyou paradise<3, my male, in another tank is loving the mirror right now! t
Hmm, the pic and description would say male as the ventrals look quite long for a female. That CT was definitely carrying something! Possibly worms or something with how skinny she was
Can you separate the betta in question(the blue one) until it heals at all? If so then when it heals you can test him/her with the mirror again when it's more lively
