we do have a marineland emperor filter as well as a whisper.. but our main filter is an eheim pro 3...... a few months ago we even bubble wrapped the support bars in the top of the tank to prevent stuff like this from happening.. good advice about the water conditions the temp is 81 F, but we'll test the water later today..
it definitely isn't a loose scale, its part of the bony plating that's part of her head.. that's why we're worried, she's dropped scales and grown them back before... we will eventually get them a 300 gallon tank, but since the jardini is small they all have plenty of space and aren't in each other's face...
thanks for the advice about the moonlight.. we have one it just isn't on.. we'll try that tonight...
with the head plate injury, should we just leave it or should we try and secure it down? i would think that would just upset her more though...
