Hi,
I'll try to explain this as best as possible. I have a 55 gal that has been established for about 5 months since it was restarted (velvet or ick took everything out in May). Everything has been great until the past week. Up until then water quality has been good. Amonia, nitrate and nitrite levels were nearly undetectable. About two weeks ago I noticed when I turned on the light in the morning that one of the perculas had been devored and had very little flesh left. I took a look at the feeder and some moisture had made it's way in and hardened the food mix so nothing would drop out. (I use an automatic feeder, spins twice a day and has a mix of stuff to accomodate different diets that I crush up). This is the first time I have seen this happen in the 12 months since I have been using an automatic feeder. I had been busy with school and wasn't paying attention to the feeding cycles for the previous few days, so I suspect that they could have gone as many as 3 or 4 days with out food. I know this is really bad, but this is the first time I have ever broke my schedule and let them go unfed. I'm not sure if this has anyhthing to do with my problem, but I'm including it anyway.
About a week and a half ago I started noticing most of the fish rubbing against things and displaying some erratic motion...I am under the impression that is a sign of parasites? However, there weren't any visable signs...no white spots or anything. (It has been at least a month since a new fish has been introduced--I know there are always parasites present but I'm mentioning this anyway) Well anyway just to be safe I did one treatment with some ick medication, and the next day did another. (I just dropped the drops in the main tank because all the fish were displaying this behavior, and so I couldn't exactly isolate it) A few days later the fish were still displaying the same behavior, so I dropped my salinity over the period of a few hours from my normal 1.021 to 1.017. (I've been told lowering the salinity is more effective than medication for parasite control) Last week I lost a yellow tang, and most of the rest of the fish started to become extremely stressed. I tested the water and was seeing alittle in the amonia and nitrate levels. (nitrites were undetectable) I did a 20% water change and threw in 5 ml of amonia detox. (for the record my last scheduled maintenance and water change was 3 weeks ago) A few days later the amonia and nitrate levels were much better, but the fish were still looking stressed. (the damsels were very dark in color and the fish were all hiding at the bottom along the sand. The yellow tang was developing some light brown blotches) At this point I put in some more amonia detox. Afew days later (tuesday before Thanksgiving) I checked the levels again and there was alittle amonia and nitrates showing, and the fish were still showing the same erratic behavior, and a little stress. I changed about 10% of the water and kept the same salinty. That night I had to head home for the holiday. I was alittle concerned about leaving with the tank in the condition it was in, but I didn't have a choice. (I'm a junior in college. Also, I don't plan on moving until I graduate--I'm an engineering major so graduation is still a ways off--so the tank isn't in danger of having to go anywhere anytime soon)
So now to the current time... I just rolled in two hours ago from my parents house. (they live about 4 hours away in the next state) The stress levels of the fish seems much better, but they are breathing really heavily, and still show the same erratic, rubbing behavior. I checked the water and the amonia and nitrate levels were pretty high. I changed another 15% of the water and dropped the salinity to 1.016. After changing the water I threw in 10 ml of amonia detox. Now an hour and a half later (just a few minutes ago) I checked the water and the nitrates and amonia seemed to improve, but still are a little high. The fish are still breathing heavy and displaying the same erratic, rubbing behavior. The coloring of the fish, especially the damsels, is back to normal, and the fish are back to their normal swimming around. However, the one remaining percula and the lyrtail wrasse are just sitting on the sand at about a 45 degree angle, not far from each other and not moving at all, breathing pretty heavily. The other guys keep rubbing up against stuff.
Does any of this make sense? I tried to recount what has been going on as best as possible. If anything is unclear, I will try and fix it. August 2003 with this 55 gal was my introduction to the salkwater side of the hobby, so I am learning more and more as I move on. This is the first time I have had trouble with the tank (aside from the major ick/velvet last May). The preceeding months excluding May have gone trouble free. Can anyone give me some advice about what is going on and what I should do both to fix the situation and avoid it in the future? The yellow tang just recently was my first loss to natural causes. (aside from the ick or velvet that caused a total tank loss in May) The few loses I have had in the past have been two to the wrasse and five to the hawaiian red lobster I used to have. The protein skimmer recently died on me and hasn't been replaced yet due to money as a result of college, but will be replaced soon.
I apologize for the lengthly post. I also apologize if some of my wording does not make the most of sense--it's 5 am, and because of this I am forfeiting the 3 hours of sleep I was planning on getting. ;) Any help or criticism is appreciated.
Thanks,
Mike
