Ee stands for elephant ear this is when the pectoral fins of a betta are oversized... It's not a disease or error in the fish, a lot of betta fish have these big fins and are more harder too find in your local petco and petsmart stores.Quick random question...what does EE stand for when it comes to bettas? i also raise chickens so when i read ee i think easter egger lol
and btw im not much of a yellow betta type but Matt yours are beautiful!!
