I've always wanted a platynemum and that's one nice pic of a stresssed one. Lol! I've a Jurense that did the same thing to me, it took about 4 days for him to regain his normal coloration.
DUring a power outage my tig started losing all his color....became almost a pure ghost white w/ no stripes. Luckily I got a generator and didnt lose any fish.
