I want to set up a tank for my nephew in a Philadelphia home but the temp. will reach 85 F + in the summer and I can maintain 68 - 75 in the winter. The room will proably get down to 75 at nite in the summer via window unit. Are there any Malawi cichlids reccomended? I love peacock cichlids (4 in a 55 now in my home) but you guys will probably know more than me.
