Quite true XR on both replies. His stocking is fine until they hit 3 inches I recon, so one more month and he will be 'stuffed'. I think our friend here needs to do more research (particularly at specialist piranha sites as he suggests) before giving advice. I recon he means no harm, he just needs time before he realises his errors. Surely he must catch on to the number of experienced and knowledge hobbyists telling him the same thing....
I think it is fair to say we are all willing to help out the less knowledgeable in this area
if they are prepared to listen to us and accept what he have to say when a number of us say the same thing. Am I right?
