hi guys , ransom i wish you the best of luck with it , and hope you prove us all wrong, the main thing you are going to need is not lenght but width , my tank is 9ft but i could still not house a micro past the two foot mark due to my limited width , you need to be planning at least 8-10 foot by at least 3ft wide as both micro and maruloides will reach 2.5ft very easy in a tank , if you can go 8ft or more by 4ft wide then you will have the most chance of it working , trying just the two micros in that size tank will greatly increase your chances of sucseeding but will still be toutch and go . esp if they turn out to be two males. the best way to try it would be to move on the maruloides now and add more micros , and as they turn into adult colouration watch them for any signs of a pair , two that hang around with each other ect. there is of course a big down side to doing it that way ,you would need to reholme the spare micros. but you could be left with two fish that tolerate each other through adulthood and a very impresive tank indeed , anyway just a couple of suggestions to think about.
ettfetbramamn -lol . maruliodes only tank would be awsome mate and if they bred for you that would be an even better sight . or even a tank with just one large channa looks great and removes a lot of the risks, iam shure whatever you choose you will enjoy it .
cheers col
