PeggyAndAl Posted April 30 Share Posted April 30 Hello! I did water change and suddenly the day after there are these white spots and streaks on the bottom inside of the acrylic fish tank (maybe snails-I never had them, so I don’t know if it’s what they leave behind)? Tank is about 6 months old and it has some ember tetras, one betta and Amano shrimps. All the parameters are good, I do weekly water change, didn’t add any new plants, etc. only thing is I did add some FritzZyme 7 when I did water change. When I wipe them, it comes back the day after, always towards the bottom of the fish tank. Thank you for any information and advices you can give me… I am new to fish tank. Have a great day!
