had a mishap in my tank over the weekend, my dats were definitely stressed and they were stable but their base color had black spotting. this was on all of my IT dats . after the problem was fixed my largest IT (15in) who's never been stable, always black throughout occasionally becoming really light colored all over (no strips showing) became stable with a solid gold base and solid stripes. he's been stable so far so we'll see how long it might last. my other dats were already stable for the most part and continue to be stable.
