What kind of polyp? A lot of corals and polyps will close at night...totally normal. In our tank, the acros put out their "feeder" polyps at night, the LPSs all close up, all the zoanthids close up, and the 'shrooms and ricordia shrink. Our sun coral is the only thing "blooming" after lights out - of course that is when I generally feed it.but my polyp closed up at dark. Is this normal?
Depends on what kind of snails and what you have cleaning your sand bed (unless of course your tank is bare bottom). If you just have turbo type snails, they pretty much stick to the glass and won't do diddly for your sand bed - you'll need some nassarius snails - probably about 30+ to start (depending on your budget). The hermits will keep your rock clean...if you aren't planning on getting a veggie eater (like a Tang) in the future, I would suggest you pump up the number of hermits too.I'm up to 10 snails and 4 hermits for a 75 gal, hows that sound for a clean-up crew
Uh...YES! I don't know what size sump you have, or if you have a 'fuge, OR what type of skimmer you have, but we've found that doing "smaller" weekly water changes is the way to go. For a 75G display, 30G sump, and 15G 'fuge, we are changing out about 13-14G of water a week.is not doing a water change bad?
Not likely. Moonlights in tanks are more for human enjoyment. I read somewhere that if you can imitate the moon's cycles, that it *could* cause some corals to try to reproduce, but I think this is still an ongoing study.does it need any moonlight?
Back to the store - no question about it!take him back to the LFS or should he meet the porcelain god?
Depends on your bio load, how much LR you'll have, etc. IMO it's better to have a good mixture of several different kinds. Can you post a pic of your tank?How many astreas would be too many?
