Im fixin to set up a 55g bottom dweller tank and im looking for some new candidates. Right now im going to move all my spot loaches (4), 3 yoyos and a burmese. Im also going to move my 6" peacock eel and a 3" madtom catfish in to. I want to get a few kuhli loaches. My biggest loach is 5" and i want to make sure he wont thing the kuhli is a big worm because ive seen him take off with some pretty big earthworms.
