Sorry to say it but yeah AEFW. That acro in the pic is done for. Get rid of it! TMPCC will be fine. QT every acro in the tank and dip away.Check under the sps for eggs also. I would also get a six line wrasse as they like to eat all kinds of flat worms, so do many other wrasses. I would try to get some Interceptor also as it paralyzes all forms of inverts. Even something as large as an acro crab, so it will kill the AEFW too. Do a dip of interceptor and TMPCC. Sorry to hear about your pest issue. I have been there with red bugs. Good luck.
