Hello this is my first time using the quarantine trio. I have been having some loss of (7 out of 8 originally)neon tetras and (4 out of 8 originally)celestial pearl danios since I purchased them noticed white patches on skin. In the same 29g tank are 2 amano shrimp, mystery snail and 8 Pygmy cories. Today is the send day of mr medication for whole tank. Which is now extremely cloudy and I have only two neon tetras, two celestial pearl danios, and about 2 Pygmy barely holding on. Is this typical?! The tank has been running since January.
