We have moved. We are based in Selby, Johannesburg.  Warehouse 3, 42 Loveday Street South, Wemmer to be exact (google maps has us as Rydawi Fish Farms both here AND at our old location in Muldersdrift so be warned!). PLEASE CALL TO MAKE AN APPOINTMENT BEFORE COMING THROUGH – we ask because we are a working fish farm and we are busy and we don’t like telling people we can’t see them right now… 

We so bill R800 for a consultation for an hour for as many people as you like to ask whatever you like of us. We’ll take the R800 off your APU purchase however.

You can WhatsApp us here
