Hi I am new to the site but have a nice 75 gallon setup with some baby monster fish. It has a glass bottom with rocks and lots of places to hide and my fish so far are, 2 rope fish, 2 fire eels, one goby dragon, a zig zag eel, a clown knife fish, a peacock eel, a spiny eel, a dinosaur bichir 7 silver dollars, 2 kissing gouramis, and 1 black ghost knife fish. They are all fairly small right now now but I will be upgrading to a 125 gallon tank probably after Christmas
