I have 4 and one is White with Red marbled into his tail fins, ones blue with purple fading into red fins, ones Chocolate with really dark blue fins, and ones hot pink with purple &red fins they all have there own characteristics, Hmm yeah one is with the other fish in my community tank just because hes the oldie and i didnt want to stress him out putting him into a betta Barrack so i left him out being 3 and a half years old now.
