It's definitely ich. Back today. Several tiny spots and a subdued guppy. Have treated the tank with a full dose as the manufacturer's instructions said that it was safe for all fish.
Have taken out the carbon filter, lowered the water level enough to create a bit of splash and have turned up the temp. to 26 as per manufacturer's instructions. Do I need to use an airstone for the otos or will that be sufficient?
The second dose is to be given in 4 days. Should I change the water (20%) before I put the next dose in?
