I dosed the 110 with Pimafix because the turquoise rainbows are looking bit rough. Shortly after, the three clown loaches immediately started behaving odd. They slowed their activity and breathing and just sat completely still. I wasn't going to risk it, so I did a 50% water change. They are behaving normally now. Anyone else experience this? I haven't had loaches since I started using Pimafix/Melafix, so I don't have anything to judge their behaviour with it by.
