These forums are here for people to learn,we all can learn,from experienced aquarists to noobs, its when we closed minded to learn or think we know it all that the downhill spiral occurs.Getting uptight over someone offering you advise is not an indication you need it or dont need it, dont take it so personally dude...If you do have a wealth of experience which you seem to imply,then please post your experiences here with these species as we all keen to learn from other peoples experiances
Deep breaths, we're all here to help each other, not pick fights. One day you may be in the shit with your tank and that same person you pissed on won't help you. Let's all be friendly please. Life is too long for short tempers.
I did see a stringray at City Pets in Germiston/Lambton this past Sunday, it had like a grey body with blue spots, I assume that was a blue spotted stingray (sorry don't know anything about them, but did look nice), maybe you can give them a call to confirm if it's what you're looking for.
Batfish I bought from Benoni Pets was very sickly. Full of white spot which I didn't see (all lights were off in their tanks). Unfortunately I didn't put into my Quarantine tank (my bad) Lost 2 yellow tangs and a powder blue as a result. Not happy and will never buy from them again.
