Very cool!!!!! Goldeye and Mooneye.....awesome !4wheelvfr;4506443;4506443 said:A proper river tank would be the golden unicorn for me lol. Very long tank with good current and fish not usually represented in zoo river tanks. Shovelnose and Pallid sturgeon, goldeye and mooneye, large catfish, and bass. I would also have a sandbar/riffle area seperate from the big river tank with darters, minnows,shiners,and other smaller fish often found in large rivers. Colorful? ......no lol, but cool? most definitely.
