Thank you greenterra, pond is approx 25000 ltrs...a bit over a metre deep and heated at 24 degrees. The jack (1) hangs out with the barra (5) and the silver perch (4) and loves his feed of chopped up pilchards every night. he probally chews the odd cichlid every now and then but dosent make any impression on the cichlid population Electric yellows have bred that prolifically that i will have to remove some of them soon.Also have some electric blues and peacocks in there as well. The jack, barra and the saratoga are probally woofing some of the rainbows and guppies as well....Balanced diet !!!...cheers...Ray
