ok, they need to start on smaller food than bbs: rotifers. I only know this cause I have reidi/kuda horses (hard to tell..) so, I don't remember where to get a roti culture... but its possible. they live in greenwater.
some people say you NEED a kreisel (sp?) type tank for these species-they don't hitch at birth and are tiny. IMO I'll just be using a ten gallon for mine when they come... they are supposed 'air snickers' so???? but ya need to keep some flow on them from an airstone... a little more difficult.
