Ok so I have a 162 gallon fish tank ((6 ' wide X 18" deep X 28 3/4" high). What ray would you reccommend for this tank? I was originally going to do motoros and build a pond for them when they get larger, but if for whatever reason in a year I can't build a pond in a couple of years I don't want to do this. That left me thinking about retics, I can purchase retics at 3-4 inches for a lot cheaper than I could purchase motoros that where a little bigger. What are good tankmates for retics that would be suitable for this tank? Also how many retics could I have in this tank? The filtration is 2 AC 110s and a cascade 1200 canister. Thanks
