Hello, from Iowa, I have been keeping yo-yo loaches for about a year now along with kulhi loaches, and over the time I have learned alot about yo-yo and kulhi loaches. And wanted to teach people what I have learned, from tank mates to food. #1 If you are getting yo-yo loaches and kulhi loaches keep them in a 40 gallon long or normall, most people say minium of 20 gallons I agree and disagree with that I keeped my loaches in a 20 long for about a year, and noticed they were getting a bit big for the tank so I moved them to a 40 gallon long and all of my loaches and tetras had major growth spurts. So I would recomend a 40 gallon long or normall for loaches. #2 Alot of people say you shouldnt keep your yo-yo loaches with shrimp and snails, but what I have found is that some shrimp and or snails but I have a single bamboo shrimp and my yo-yo loaches have not bothered him at all, for snails though I dont know if the loaches will bother them or not I havnt had any snails yet but I am hopefully gonna buy some snails. I am going to get some hillstream loaches soon what kind you recomend for my tank set up and how many I should get?
