My fat copperband butterfly

[daniella3d]

I am going to treat mine for flukes and internal parasites with prazipro for a week before introducing it to my main tank. That kill the flukes and the internal worms. I doubt mine has internal worms because he regained weight so fast and easily, but you never know. Better be safe than sorry.

Usualy the head twitching is caused by flukes but I have also read that if they are upset or scared they can swing their head sideway.

I find that with copperbands, at least the ones I've had, always seems to be something on the inside that does them in., last one I had started head twitching, lasted a week.
