I bought 6 Kuhli Loaches on wed and Saturday night and Sunday night i found one dead each night with its skin stripped i attached a picture, my stock is 8 Platys, 6 Zebra Danios, 6 Neon Tetras, 4 Albino Corrys and now down to 4 Kuhli Loaches in my 72 g Tank, they are juvenile Kuhlis very small but i didnt think i had anything in my tank that would eat them it always happens at night i check the tank before i go to bed so i suspect the corrys
