Wow! south Africa? I guess I glanced, I thought it said south america! lol, I pictured you south of me. This really is a world wide hobby, that is just too cool.
From what I have been reading rotifiers are pretty much the best food source for the clown larvae.

Is not a live food but is supposedly suitable for feeding larvae. So once I get to that point in a couple months hopefully, I will find out.
It looks like about $40 per bottle on the 16oz bottle and says suggested feeding is about .4oz per 100 gallon, I am guessing that is twice, maybe three times a day? How often do you feed Billsreef?. so on my set up which is half that more or less a bottle would last me about, hmmm..., .2oz per serveing, three servings a day equals .6oz a day, or 4.2oz per week, or 16.8oz a month, so I would be like 1.5 days off from a 30 day cycle per bottle. If the Experation date will make it, I would be happy with that!
I increased my cost by $40 bucks a month, but saved myself a lot of time, and experimenting with raiseing live food.
If anyone has used this please chime in and let us know!
