As cool at the larger loaches are, I think the smaller ones are far more entertaining. They sometimes "ride" my other fish. They get right on top, or beside another fish like in that video and stay there as long as they can and nibble at them while they do it. I'm sure it doesn't cause any damage, but it's probably really annoying lol.
It's fun with all of the different sizes interacting with each other. I have loaches ranging from 1.5" all the way up to 10"+. I started with a group of three medium-large sized ones, then added 5 small ones from a Petsmart sale. I then found a group of 5 large ones for sale from a local hobbiest. For a long time my smallest loaches thought they were Rainbowfish. LOL
Hello again Psylant! That was a great vid. The little guy staying right on top of the big CL was so cute. The big one was like will you stop already? Cracks me up. Love your Centrals too. Your tank looks super!
