Good aggressive large tank created?

I am currently building about 55 a gallon. aquarium tank want to be a little aggressive, so two main fish with an additional guess maybe a few fish feeder fund and some other things. Fresh water is heated, filtered with plants probably false and some rocks in the background. What are some good fish attraction it might have on a tank of that size? I have experience with fish and brackish water tanks. Also I can make the tank bigger or smaller to fit a fish needs. Thanks for your help!

Well, first of all fish to be cichlids. Now the first thing that came to mind was an African tank with different species or a harem of a kind. But then I started thinking. If you set a theme name that could be great and a safe with a large tank. First, there needed to cover the deposit mostly out of wood, rocks and plants. Now make sure water quality is fully cycle with a constant pH of about 6.8 which will be good for a number of South American dwarf cichlids. Now for the fish if you have a type of many different cichlids that would be absolutely amazing and would not play as not only be a little territorial aggression, but nothing major. Some dwarf cichlids would be good: – Apistogramma agassizi (I think that's how you spell it) http://laquacavederemou.free.fr/RMG/B/wallpaper_cichlidpress/amerique_sud_centrale/apistogramma_agassizi_01b.jpg – Cockatoo cichlids% 20Full% 20Red% http://rare-tropicalfish.com/Common_Tropical_Fish/Cichlids/Double 20Cockatoo% 20Cichlid.jpg – (long-finned variety pictured) http://www.aquaforum.nl/gallery/upload / microgeophagus_ramirezi_male Rams. jpg – Curviceps cichlids (I think it is also called Dwarf flag cichlid) http://images.google.com.au/imgres?imgurl=http://www.aquahobby.com/gallery/img/Laetacara_curviceps_3.jpg&imgrefurl=http : / / Www.aquahobby.com/gallery/e_curviceps.php&usg=__0XFcmE7-SzXcUAwDshzdijSB-wM=&h=332&w=500&sz=30&hl=en&start=1&um=1&itbs=1&tbnid=XioYKH8NJY4dgM:&tbnh=86&tbnw=130&prev=/images% 2Bflag 3Ddwarf 3Fq%%%% 2Bcichlid 26um% 3D1% 26hl% 3Den% 26safe% 3Doff% 26rls% 3Dcom.microsoft: en-US "search box IE% 26rlz 3D1I7GGIE_en% 26tbs% 3Disch%: 1 – Any http://www.flickr.com/photos/55011269 @ N00/2240125904 Apistogramma / research a little about them and in general South American dwarf. On top of that (Of course not get a cichlid million) would put me in a school of corydoras cat (aggression would not so much because there are no playback) and a school tetra your favorite. So the school would not be beautiful active tetras and Corydoras school. While this is happening cichlids would have to protect the territory, throwing around and doing all the things you should cichlids. And depending on the amount of fish you receive are likely which could put in another thing. Best you can do is talk to a reliable fish store on this idea and see what they suggest. That to me is half of sleep. If you choose my idea it would be great to hear how goes. Goodluck
