I just got a Chaca Chaca around 3 1/2" and was wondering if anyone else has these cool lookin fish. He's in a tank with some Asian RTC's a Ompok and 2 False Jaguars(Liosomadoras morrowi). Anyway this is my first time with Chaca's and was wonderin how many they're are out there and what are your experiences. I can't wait till he gets bigger and I can put him in my other tank with the white sand. Right now he's in a grow out tank with blue sand and he just doesn't look right in there.
