These guys have been through a lot as their tank cycled. They have suffered with varicose veins in their tails and cloudy eyes. Thanks to Fishlore they have made a wonderful recovery. The Melafix medicine really works. The water conditioner "Prime" really works. The water changes really works. I also put in an ultra-violet light/pump which killed the bad bacteria and made the water pristine clear. Wabi-Sabi, Sun, Bubbles, and Mojo now have clear beautiful eyes and pretty fins.
