Black Widow Coloring

[ShaneO]

Seeking some advice... My Black Widow has lost some of its color/webbing over the last two months. Any ideas? Too much light not enough? Or something else?? Light is a hydra 26 about 13" off the top of water of my 20g nuvo with intensity about 45ish. Parameters of the tank are stable. Also feeding twice a week ( LRS, mysis, raw market shrimp). Any help or suggestions would be great. Thanks in advance!
Posted pics are when I got it and it currently. Roughly a 2 month timeline.

I'd stop feeding it. Just feed the tank.

I'd try slowly increasing light or adjusting your spectrum and see if it helps. The nem looks healthy.

I think we may be chem warfare with the other bta. I also have it with other bta as well. Been changing the carbon every week to combat this.
