powder brown laying on sand bed

[naesco]

If he has ich and he is lying on the bottom you only have one choice.
Set up a QT using the display tank water immediately.
Put her in the QT and place an airstone near her.
Use formalin and be very careful to follow the directions.

If formalin is not available use malachite green. If not available you have to do a fresh water dip (same temperature and PH)

The reason she is on the bottom is that she cannot breath owing to the fact that ich has restricted her gills. Extra oxygen via the airstone helps a little but the ich must be killed by the formalin.

Good Luck
