Here are a few freshwater fish I have my eye on, FW Ray, Borneo Sucker, Black Ghost Knife, Congo Dolphin, Peacock Gudgeon, Clown Loach, Elephant Nose, Baby Whale, Whip Tail, Mix of Tetra and cherry barbs, and I found a company that offers an alge squad of nerite snails, flying fox, golden alge eaters, red cherry shrimp, amano shrimp. I have a 100gal tank that I'm looking to go with black sand or smooth gravel with small to medium caves for hiding spaces.
