I can't keep fish alive. help please

[GPhiAce]

So, I think my sixline is doomed. At 3pm today he was great, swimming fine, picking at rocks, just great. At 7:30, it looks like he got in a fight and he is back swimming odd (maybe because he is missing parts of his fins now). check the link http://s250.photobucket.com/albums/gg268/GPhiAce/.

I stopped the metronidazole mixture from fishdoc 2 days ago. Does this look like he was picked on?? And by what?? My livestock include 2 percula clowns, 2 emerald crabs, blue legged crabs, snails, maxima clam, and a lazy brittle star fish.

Guys, I need some help here. Not having any luck with keeping fish alive. in the past month I bought and lost a citron clown fish and green chromis (both died in less than a week), and now the sixline may be next. I did get them all from the same place, and acclimated them 3.5 hours each using the drip method. I was thinking of getting a Randall's goby and pistol shrimp. Don't think I shoudl get anything else since I can't keep what I have now. Any thoughts

Those are those body ulcers I was tellling you I had on my Bellus. I would start that food again if you still have any. It doesn't look good. Most fish I've had with those have died. I saved the angel but it took several months.
Marine fish are really hit and miss and I don't think it's anything you are doing. Lots of time they are sick when you get them and it's not yet obvious. The only suggestion that I would make is when you get a bigger tank keep the 29 and QT all your new fish. When the tank gets full you can take down the QT. That's what I do anyway. LMK if you need more food. You probably also need the recipe. Remind me tommorrow and I'll give it to you.

I have a ton of thoughs, what are you specs? Sounds somewhat like ammonia burn to me, have you had anything die lately? I personally think a drip of 3.5 hours is a little long, I usually run about an hour. It may not be you, it may just be the LFS and the fish. The chromis are really not that hardy, some are some are not. The citrons are so small there could be numerous causes for death. The sixline is what I am wondering about as generally they are on the more aggresssive side and he looks like he is really well fed. Not too much could tear a six line like that up so I think it is probably an infection and agree with fishdoc totally though it could have been from other causes.

Thanks brad. the sixline died about a day after the posting. the specs came back fine, ammonia was less than 10 ppm, but that was a spike from my usual 0. Trates- 0, trites- 0, alk 10 dKh, sg 1.024, ph 8.2, Ca 420, temp 76/78.
