I officially got myself my own tank, so of course i have questions. I have a juvenile jd in a 55 with his odd but inseparable buddy a zebra cichlid. There is also a few giant danios, a lonely tiger barb, and a peacock eel. I was planing on adding a juvenile jag, but that's where the question lyes. Would there being any over stocking issues by adding a jag to the mix? Now i know (and hope) the danios will disappear mysteriously. My buddy at my whole in the wall pet store says it shouldn't be an issue but i thought i would ask. Also want everyones views on air pumps for these fish, example how much air flow style of hoses placement etc. thanks for anyone who responds
