ok so I have had these guys for about 5 months. my friend traded me for some stuff and he breeds fish and he told me they are electric blue and dolphins. I got about 25 of these guys. Super healthy. about 1 inch. $2.50 each but I prefer if someone buys all so they know it's half and half. you can't really tell what's what. starting to show some colour. eating everything. I can send pics . just text me at 604 760 5247 if interested.
