120 gallon build

Hey everybody,

I've posted here a few times and always got good info so I thought this would be the place to go. I have a 29 gallon mbuna cichlid tank and I'm planning on expanding into a 125 gallon within a couple of months. I also want to raise a baby arowana for my friends 250 g, he can't really add any juvenile fish. Plus i really want to keep an arowana at least for a while. Do you guys see any problems with the combo of mbuna and an arowana? And what's the growth rate of an arowana? Just so I know when I'll have to give it up.
I have plenty of experience with aquariums my size and smaller but I've never tried a large tank, is there any advice or common problems I should know about? I definitely want to use a sump, and I hope to eventually add a large amount of plants. I haven't had any problems with my cichlids eating any of my plants faster than they can grow. Any advice on substrate?

Well... First off (as a keeper of mbuna) I just want to say that that 125 is going to be awesome. But from there... I have to say I definitely wouldn't keep an Arowana with mbuna. Not that I know they wouldn't get along or anything... just simply because Arowana and mbuna require drastically different water parameters. Arawana (being from the Amazon) require soft, acidic water, and mbuna prefer hard, basic water, aside from that, I'm almost certain that they grow pretty quickly, so you shouldn't have to hold onto it for long... As far as advice goes for a larger aquarium... I doubt that there is any to give. lol. The bigger the tank, the easier it gets. If you're used to tanks smaller than 29g, moving up to a 125g should be about 10x easier. I wouldn't advise putting plants in the tank with mbuna either however because (as you said) they'll eat them, but also the waters of Malawi (at least in the areas where mbuna live) are nearly devoid of plant life. I find that just filling the tank with rocks (nearly anyway) makes for an interesting decoration on it's own. With substrate, I use an argonite and black sand mixture to help with the hardness and pH, as well as bringing out the colors in the fish.
