All, Which fish suitable for smaller tanks (45 gallon) are the most fun to watch? Setting up a 45 gallon tank (Max E 170) this week that I will be stocking with fish in March (going to cycle this thing the right way). I have always been more interested in keeping fish that are interesting to watch, not just pretty to look at. I'm planning on doing LPS, softies, and having a large clean up crew (they are fun to watch). To be honest, the inverts are the most interesting thing to me (I love hermits!). I'm getting back into the hobby after a 10 year absence and there are quite a few fish new to me available to me now. I'm thinking 4 0r 5 smaller fish (added over months) and am looking at easier fish to keep. I'm thinking a 6 line Wrasse, a Royal Gramma (or Neon Dottyback), a yellow watchman goby, and maybe one or two other small fish. Other than the obvious answer of clownfish (don't have much personality IMO), what would you recommend (added responsibly over time). Also, any suggestions for alternatives similar to the 6 line wrasse?
