I have been doing some reading on here and other sites about getting some loaches to help assist me and snail traps in my 110 gallon 5 foot long low tech planted tank. Currently it is stocked with 7 Panda Cories, 3 Pepper Cories(3-4 more in the future), 3 Adult swordtails and an unknown number of fry, 12 Neon Tetras(at least 20 was the plan), 4 Harlequin Rasboras, 4 Zebra Danios, and 4 Oto's(plan to get 3-4 more). As far as loaches go I know I can get 4 clown loaches for $20, and I know they get big. Other thoughts where 3 Yo-Yo loaches, it seems they can be happy in a group of 3 from what I have read, or Zebra Loaches around 5 of them. The system does run on the warm side here in Florida, in the summer it's not unusual for it to be pushing 81 Fahrenheit. I'm leaning towards the Yo-Yo's since it appears I don't need as many and they don't get as big as the Clown Loaches.
