Fish dying when added

[freshwater]

I am running this 72G Bow front for 6 months. for last six weeks whenever I add new fish they died in few days. I have clowns, damsel, fire fish and scopas TanG. I added a naso, blue tang and a powder brown tang during a period of 6 weeks but they all died in few days, They dont eat much, got some thing like ick which looks very bad in the end like eyes all blury and then they died. My scopas do chase them out for first day,but tank has enough hiding places. I also lost a cleaner wrasse and a damsel the very first day never saw them again.

salinity = 1.0025
PH = 8.1
ammonia=nitrite= 0
nitrate ~ 20
phosphate ~ 1.0
calcium ~ 450
food, nouri, brine shrimp, flakes all dip in Garlic extract.
lots of cleaning crew

Do you think i should add UV sterilizer which might help? OR any other ideas.

Thanks.

That sounds like your answer right there. They are all getting ich. Most tangs are ich magnets and that is too many tangs in a 72 gallon tank (this would just stress them more and accelerate the ich problem). The Blue Tang and especially the Naso will get too big for the tank. As for the Powder Brown, they don't have the best track record for survival/acclimation in captivity.

I would wait awhile before adding anything and then try something other than more tangs. Maybe a wrasse?

I would say that tank should run fallow for two months, and ALL new additions undergo 30 day q/t (minimum).

Waiting is definitely your best bet. 6-8 weeks minimum, or longer if you have the patience. A UV sterilizer will help to some extent, but it's not gonna solve the problem completely. Test a few hardier fish when it is time to reintroduce, and add them slowly to monitor each's progress. A QT tank, as SM suggested, is highly recommended.

Also,

Not one of those tangs is suitable for a 72 bowfront.

PBT and Powder Browns need tanks of AT LEAST 100 gallons with VERY STRONG current and lots of open space and they need to be QT'd before adding to the tank ( as should ALL of your fish)

Naso tangs get to be well over 1 foot in length ( some reach up to 2' ) and really need tanks of several HUNDRED gallons to do well long term.
Whoever sold you a Naso tang for a 72 bowfront should be taken outside and beaten silly.

A bit strong, don't you think

But it is true a 72 gallon is on the small side for Naso and Acanthurus tangs. I'd stick with Zebrasoma tangs. These will eventually outgrow a 72 as well, but they stay a lot smaller for a lot longer.

Sounds just about right to me. :wink:

You may want to change your source of fish as well if all these fish came from the same LFS.

Before resorting to beating your LFS owner you might want to keep an eye on temperture swings. I notice that you are running 2 MH's and a couple PC's over your tank and now that the weather is warming up a temperture swing can contribute to ick breakouts. If you don't already have one, a chiller would be an exellent investment

good call jime,,


feed all of your current inhabs with garlis, ZOE, ZoeCon or the selcon alternative.... watch your swings... then get a QT tank...

I am gonna QT all of my fish. I have learned my lesson. It is best for the fish and best for the tank....

We QT SARS patients before public contact. we should do the same with our fish
