I encourage anybody to at least try a cray they are too neat.
P.S. Ciaobella Sometimes they just cull out the weak fish and leave the strong alone. But then sometimes they just go for the brightes and slowest. My male guppy just got caught. Rip lil fishy. But he got to my women 1st so maybe I will get a male from his spawing. Sad to b/c he lasted longer than any other male. I thought she wasn't interested, FOOLED me.
