dead tangs

[slb11106]

i dont understand,
i got a sailfin a month or so ago, it lived about a week or so, eating fine active then lost color and died

almost two weeks ago i got a PBT and it died this morning, it was also eating fine very active and colorfull. it had a horizontal line on his body (i thought it was just not eating enough) well it died and i dont know why

i have eight other fish 4 shrimp, 2 crabs, 4 corals (soft) all perameters are great...(nitrates 0 ,nitirtes 0, amonia 0, cal 400, ph 8.2, kh 12)and they all have been in there a while and they are perfect ! just seems to be the tangs, anyone know what the *#$% is going on with them ?:cry1:

this is very disturbing to me, might it be that they were doomed from the start ?maybe cyanide collecting or something.

whichever LFS you got them from should be able to tell you where the fish came from, that will be a better clue to how they were handled

I am very sorry for your loss.

Tangs are very suseptible to ICH, they will get it in the gills and suffocate if not treated, this is not always the case but it could be a factor. Tangs also have a tendancy to get stressed easily, it takes them some time to acclimate to there new home this is one of the reasons they are so suseptable to ICH.

Did you get both tangs from the same fish store? Also as mentioned above where did they come from before that?

When you say they where eating... what where they eating? Are you feeding them any greens (spinich leaves, nori, etc)?

What are the other kinds of fish that you currently have? Tangs also have very high oxygen demands and may be the only ones showing the effects if your oxygen levels are low (like in a closed, high temperature system). Something else to check in addition to what others suggested above.

How often do you do water changes,and how much do you change ? Ted

Where did the fish come from?

the fist sailfin came from marine warehouse on hillsborough rd, the second pbt came from a place on waters near dale mabry, i forget the name (actually it was the first time i purchased from there....and the last, but i bought the pbt for 30.00 which was very cheap, and now i know why.

I kind of agree that low O2 levels may have caused their death. Tangs are usually the first ones to go, and sometimes the only ones. However, I would expect your pH levels to be a little lower since CO2 accumulation would drop the pH. Unless, you've been dosing a lot of buffer recently. If that's the problem, an easy solution is to point one of your powerheads upwards to stir up the surface. Some people also get a fan running over the surface of the tank.
