I shoot a lot of macro photography, so thought I'd weigh in on this one.
You've got a lot of really awesome shots in there. You're capturing good angles and at the appropriate aperture settings to get the right depth of field for your subjects. I can offer some very small suggestions as well, but honestly there is very little to nitpick about. Really nice job!
I think there's a couple shots where you might want to watch composition of the shot assuming the critters cooperate. I know what it's like trying to chase them down with the camera, and sometimes you're very lucky to get what you get. lol
Anyway - an example would be #84 on that last batch. The shrimp looks good, but I think the shot would be stronger if shifted to follow rule of thirds with the shrimp in the right hand side rather than centered. Shifting the shot in that direction would also pull more red into the left side of the shot, creating nice contrast and a more striking image. Also I think the shot needs a bit more light - it reads a shade dark to me. I played with that shot a little bit - just slightly adjusted shadows/highlights and contrast, and then did a crop to help illustrate. The differences are subtle, and you can decide if you like it better or not.
The other critique I would give is that I think you need more light in general on the underwater shots (primarily mid-lower tank levels). A lot of them feel too dark. If you don't have extra lights, but do have something like photoshop, you can do some small corrections to that in post production, esp if you shoot RAW (it's a lot harder to adjust a jpg file correctly). You can also check your camera settings and see if you can adjust the in-camera light metering for those underwater shots. Also, for plant-only shots a longer exposure on a tripod would also work.
That's really about all I could see to suggest. Again - you've really got some great shots in there, and you should be quite proud of the the pics you've taken, especially with subjects that move unexpectedly.
Some of those shots are really quite stunning! Great job!
