Tamarind Bonsai Care

So I picked up a tamarind starter today. I hit the net to do a little more research but I can't fin much of anything helpful. Does anyone have a tamarind? Any secrets to their care? fertilizer? pH? etc. Any information is appreciated.

I found one site that had a vague care guide. It listed a pH of around 5.5 and to use an acidic fertilizer. I'm not sure if this is correct or not though.

Thanks
