for the past 2 mornings, i woke up to see white spots that look like worms on the side of my tank. a short time after i switch the lights on, they are gone. i am afraid that this may be the reason i am finding a dead shrimp or 2 everyday. i tested the water. ammonia 0, nitrite 0, nitrate is .25 if that. my Ph is at 6.4. i have my temp at 75 and all i have in the tank is dwarf baby tears.

has anybody had this problem and what can i do to fix it? open to all suggestions.

thanks
