I am looking to add another tank to my home and need some suggestions. I am looking at either a 55 or a 75 gallon tank; either one done with as a freshwater community, stock open for suggestion, or a cichlid tank, with suggestions needed for algae eaters and bottoms feeders. I have only had 10-12 gallon tanks so far and have not had anything this big, so I also need suggestions for tank size, filtration and aeration equipment, lighting, and decor. I am a cabinet maker so I can build the stand myself, I am planning on making a custom one for my daughter's 10 gallon soon. I really would like to do the cichlid tank, because they are probably to most gorgeous freshwater fish, but I have no experience with them so I was also thinking about a community tank with at least one shark. If you have any suggestions please let me know. Thanks.
