Hi Andywoolloo,
I agree, they're just ridiculous little clowns. It's taking away a lot of time right now when I should be doing other things
It's like they have wind-up motors in them and will take a giant leap into the big world once in a while and motor along the wall, down to the bottom, across the sand, up the rock around the corner....whew! All the while they're wiggling away like something is chasing them.
The big black syno must be a mom or a vegetarian

They seem to stick right up against her (him?) most of the time. Right in the same hole. If I can't find them, that's where I shine the flashlight and sure enough, they're right up against her. I even checked the temps with another thermometer just in case it was a warmth thing.
Last night I saw one of them ride the rock face down to where the big whiskery snout was sticking out and actually bump right off the tip of the syno's nose and sit there for a minute like it was stunned. I laughed so hard I snorted out loud

, all the while terrified that one gulp and goodbye little guy but no, the little guy just geared up again and motored away.
They sometimes cruise around the rock and brickwork like a little wiggly train but I noticed two of them fighting??? I thought that I was going to have to scoop one out but the chance of that happening without emtpying the tank if zip to none. So I just watched and gave them a puff of water with the turkey baster into the brickwork hole and they soon broke it up. I guess just playing or fighting for a good spot?
I am planning to upgrade their tank and get some more!
If they stayed like they are now, I'd want 50! As is, I'm getting rid of the desk in that room and moving my comfy chair in. I guess I may as well just cave in and buy a laptop so I can work in there...Good thing the main tank is in the living room otherwise I'm afraid I'd ignore them a bit over the next while.
Racing, shoes and fish. Nothing else matters. Oh, and bacon.
