there are some umbees I saw at the fish store for 30 bucks. They are about 3-3.5 in.. They all seem to have speckles on them already. There are some darker ones and there are some lighter yelowish (just slightly) ones. And I lighter ones are a lil more aggressive then the darker ones. Maybe the dark color is from stress I dont know. They look very healthy to me and I want to get a male. So at that size, can I look real close and find the difference between a male and a female?
