So I got a 125 gallon a few days ago. And I want to get some stocking ideas. I really like the fire mouth cichlid, but I also like peacocks and Mbunas. I want to do a cichlid tank but I want the super crazy bright colors. So far those are my options, but is it possible, will it be okay if I do a mixture of peacocks a and maybe 1 or 2 fire mouths? Any other cichlid recommendations that are super bright colors that I could do? Also is it okay if I do black gravel for my substrate? And do I need any decors?
