i decided today that i would buy some africans and do an african cichlid tank. i have a 55g thats been set up for probably a year with various fish in it. the tank is empty now and the fish are floating in the tank. i bought 4 mixed africans, 3 livingstones, and 3 electric yellows (2 of which looked like they were spawning in the tank). all of the fish are about 2 inches long. ive never done an african tank before, but have seen pics of rocks piled on top of each other. im guessing that is how i should decorate the tank? i have lots of clay pots and pvc pipe, should i put some of those in there? im guessing plants are a no-no. as for stocking the tank, isnt it best to overstock to spread out aggression? a few of the mixed africans are going to get large, as are the livingstones, so how many fish total should i look at putting in there.. maybe 10-15 ? they were kept at 7.0 ph at the store, and getting them used to a higher ph will stress them out, so i assume i should just leave the ph of the tank at 7.0. any ideas/info/advice anyone can contribute is welcomed! thanks
