They aren't anything named that I know of, well three of them anyway. One of them is a green slimer. The other three are just acros. One is dark blue, one is redish with blue tips the third is yellow with neon green tips.
Unfortunately I fell on Friday and have injured my back to the point that I can't walk unsupported. So, I'll not be doing much of anything to the tank this weekend.
Anyway, all is well with the tank. I have a coral in the display that got knocked over but other then that everything is looking great!
