I recently started up a 20H SW tank, which I'm planning on building into a "seagrass" biotope, composed of some LR, macroalgae (species that spread over sand rather than rock), and plastic Vallisneria to stand in for seagrass. Currently I've got 2" sand and ~15lb Florida LR I got from a friend, which has some small SPS (Porites and Turbinaria I think) that seem to be doing well with my current low 20W NO lighting. I have an empty Aquaclear 500 HOB running that I'm going to turn into a mini-fuge, but I'm not planning on getting a skimmer. For added inverts, along with snails and a few hermits, I might try some Sabellastarte tube worms. So, given all that intro, I'm trying to decide what fish would be best to add - I'm just going to add one. I'd like something that will have a low bioload, be hardy, and will do well in the unskimmed "seagrass"/macro/LR setup. My ideas so far are:
1. Neon gobies (Gobiosoma spp) - tank-bred
2. Clownfish (percula or ocellaris) - tank-bred
3. Small wrasses (Six-line seems very popular, flashers maybe? - not sure if 20g is big enough for any of these)
4. Trimma/Eviota gobies (I don't know much about any, except that they're really small)
I'm leaning towards neon goby as the safest choice, but the sixline and flashers are so beautiful. Any advice on these or other options would be appreciated.
Thanks, Ryan
