ok so i have a 200 gallon coming in next week and im either keeping it or selling it for more than i paid for it or keeping it. im getting a eheim pro III to start of with and all the bio media. i was going to get the cichlid gravel to make the water more hard but i might eventually get a pleco so thinking sand, what do you guys think? im going to get a few big hunks of lace rock and thats about it. i already know im going to mix the lakes because the fish never read a book that said they cant be in the same tank. anything i should know about? how many fish should i start out with? just pretty much anythingggg i need to know as i have only had a community tank before. i work at **************** so i can pretty much get any kind of cichlid too
