Unfortunately, the only flare pic i have is the one below which is really bad quality and also her tail has been pretty chewed (shes the one on the top of the pic). I've now had to split them into their own tanks from the quarentine tank they were in together before i put them in the community tank.
The one below I think is a BF VT (??). I guess you cant tell from that pic what the blue one is now?!
my female betta that i bought is quite similar to the one your trying to i dentify everyone i asked they said mine was probably a delta mine is green and blue and still a baby.
