I name all but the ones I can't tell apart then it's just the group or something.
I have: speckles, domino, snowflake, dusty, Mickey, Otis (both my Otos), azzie, and spot. Other than that it's just not named or something. My cardinal tetras were stripe x I had stripe 1,2,3 and then 1 and 2 died so then I had stripe 3-13 til they died and I haven't restocked with anything yet. My corys are Leo leopard and then zebra even though he has spots and lines lol can't really tell them apart too good though other than male to female.
