These are I'm guessing 3" or maybe a tad more. They are freshwater fish. I'm selling because they are picking on my crayfish. Well one is but I'm sure the other is when I'm not watching. I'll take $5 for both of them or trade for some other fish or a nitrate test kit or something. I have a close-up of the yellow one but the blue one is more off in the distance. The yellow is a female, the other is a male.
