| | Dead fish, Foam on the water and brown stain
If you read my previuos post 3 weeks ago, i had i betta, 5 dwarf gouramies and 1 opaline and 1 pearl gouramies
i removed the opaline and the pearl
them my 4 remaining gouramies and fbetta, started to die a week ago
now i have a lonely dwarf gourami in the tank
i checked for excess ammonia, but levels are fine, there's no sign of disease(at least as far as i know) but i noticed this small amount of white foam on the corner of my tank plus there's a brown stain on the back wall of the aquarium
DOES ANY ONE KNOW WHAT IS GOING ON?!!!!
THANKS A LOT
