Here's a wider shot of more of the tank. I've cut off the extreme right of the picture/tank because the flash reflected off the glass and bleached it all out.
I'm intending to shift the slates on the left a bit, break it up into smaller pieces, stacking it more at ends and creating more run throughs. But at the moment the Cherry Shrimp are holed up there, as the Danios are paying them quite a lot of attention. Don't think they're a good mix, or at least not until they grow a little. I've one particularly boisterous danio and, being larger than the others, he tends to charge around like the proverbial bull in a china shop. Also has quite an appetite.
