I have 7 loaches and one of them likes to hang out with my biggest male frontosa. The frontosa is around 12" and the loach that hangs out with him is around 3"......
mine try to swim with my tinfoil barbs lol. they also try to "suck" at or pick at my cichlids, as if they were trying to eat off their scales. the cichlids dont like this one bit. very amusing to watch lol
Mine sleep and school with my little peppered Corydoras, and sometimes lay on them. I have 12 loaches and 4 cories and they all make up one big happy family lol.
