Is something wrong or is she just ugly?

Year old tank stocked with galaxy rasbora fry and a ramshorn,

0 ammonia 0 nitrites 20-40 nitrates depending on fertilizer schedule, 7 gh 35ppm kh 7.7 ph

Was just doing some plant rearranging and she caught my eye. Her tail is such a weird orange/brown color, her trunk is more opaque, her head has this see through spot that looks a lot more see through than i remember, and under the tip of her tail is turning dark.

She literally looks like she’s half cooked. Is she just ugly? Or is there something wrong? I had a mass casualty event last month after lowering my GH too quickly trying to help my sick galaxy rasboras.
