HI, ppl i got a 2feet tank. House with 50 malayan shrimp, 10+ plus fire red, last 2 week , few malayan shrimp turn white, and i often find dead shrimp within few days, funny thing is the firered did not get the same white things as the malayan shrimp, i have 4 neon tetra, now left about 30+ malayan shrimp and 10+ firered, any bros out there knows whats the white stuff?
