I bought Blanca here as a VT female at Petco. I had to snap her up, because when else was I going to get an EE for under $3? Anyway I knew she wasn't a VT and since getting her home have started to wonder if she is a she.
I put Blanca in a sorority with 3 other females. At first she was the mother hen of the group and would break up fights. Than I had to remove one of the females because the others were ready to kill her. When the sorority had 3 females (I know it need 4 min) Blanca built a large bubble nest, taking up a quarter of the tank. After building her nest she stood guard and if another female came anywhere near her she attacked and chased them all over the tank. In the end I broke up that sorority because the females I had just were not going to live together.
When I put Blanca in a divided tank with a male (tried this with 3 males and got the same reaction every time) they would go nose to nose at the divider. While the male flared up Blanca would just look at them, then swim away. I have only ever seen her flare when I had her in the sorority and she was breaking up a fight our guarding her nest.
I know there's a lot of more educated people on here and likely have a better idea than me of the sex of Blanca. After seeing her reaction to other males I strongly lean towards her being a female. I haven't been able to get a pic of her flaring, but here are some of my best pictures of her. Does anyone have a pic of a male EE? Maybe if I could compare it would help me be sure.
My other question is what kind of EE is she? Plakat (sp?)? HM? Delta? Something else altogether?
