And now I know better
I also lost my royal gramma (my first SW fish) because I couldn't catch him until it was too late.
But now I have the dirt cheap hospital / QT tank: hunk of base rock, PVC tube, 5.5 gallon tank, sponge filter and air pump. One clown's looking better, and the other one ... well, his colour's improved ... but I'll see how he's doing by morning.
But I do have two questions, 'tho. How long to keep the clowns in QT before moving into the (now fishless) display tank? How long before the display tank is disease-free?
