So i have a flame angel in QT. It had a serious case of the twitches with no obvious sign of anything. I formalin dipped it before it went into the QT. So I did a round of treatment with NLS Ich Shield and Prazipro. Its on the third round of PP and every now and then the fish will give a slight twitch. Its not scratching or flashing. So whats the deal with twitching, is it always a sign that the disease is still present. Do flame angels or other types of fish twitch for no real reason from time to time?
