All my fish dyed

[benjidick]

Purchased new yellow angel. In one week , without much food, the fish was swimming in the conner with his head up. Needless to say fish dyed two days later. Three days later my nemo dyed,and in four add days my blenny dyed. The yellow fish had some kind of desease. How long should I wait to try new fish??

Getting new fish is the last thing you should be thinking about. Your tank is probably contaminated with ich. I would recommend removing whatever left alive and move them to a hospital tank and either treat them with copper or hyposalination

[fattyratrat]

did you cycle your tank at all? You should not have had either of those fish in a 30 gallon tank either, so that probably didn't help.

Did anything survive?

[ihavtats29]

what are your water parm's?

[benjidick]

No evidence of ich. Tank has been cycled for three years. Water conditions fine. 5p/m nitrate,1.024 salt,8.2ph,calcium 400,kh165.

[fattyratrat]

oh oops.. sorry my brain registered nemo as dory.

[Salty Joy]

Let the tank run for at least 6 weeks before you put anything else live in it. Change carbon once a week.

[benjidick]

all fish dyed. only 2 crabs alive.

[benjidick]

One further item. Tank has 70 % 0f bottom covered with live rock.

[ihavtats29]

If all your fish died that rapidly, I HIGHLY doubt your water is "fine"

Have you tested for ammonia yet? Also I would take a sample to your LFS to have your results confirmed.

In the meantime I would do a large 75% or greater water change.

What type of substrate are you using?

[benjidick]

Checked ammonia , 0 found

[Playa-1]

Maybe Brookynella

[peterpaul]

I would add carbon to remove any unwanted or harmful substances. Do a water parameter check like copper and so on. Also do frequent large water changes to try to reduce any other toxins that remain and let the water stabalize.

Slow down .. do some research .. let your tank go fallow for 5 weeks, purchase one fish at a time and QT each individual fish for 4-5 weeks .. don't buy difficult fish like butterflies until you are experienced and have the proper tank.

Hobby Experience: 10 yrs saltwater????
You're kidding.....right?

[weluvfish54]

new to the hobby after 3 year old tank...?

[Rendos]

Before you added the fish, were there already other fish in the tank? Have they died also? If there were no fish in the tank before you added the ones listed, how long was it running without fish?

The yellow fish had some kind of disease - what kind??? Describe it's symptoms.

[benjidick]

New to the death of fish.Have lost fish in the past ,with high nitrates and other toxic conditions. Known water conditions in Past three years had lost only 2 fish. One Blenny and coral beauty. Failure of quarentine by fish dealer and my haste to replace coral beauty led to problem. Just wanted rec. on time and water clean up prior to new fish. Plan on blue tang,flame angel and another blenny.

[otrlynn]

If all your fish are dead, this is an ideal time to let your tank run fallow (fishless for 6 weeks) so that any disease or parasite will have no host. If you have ich in the tank and immediately add fish, chances are they will be dying of ich or whatever, within a week or two. After you do a couple of good water changes, you may want to add to your clean up crew (2 crabs are not much). Make sure to acclimate them slowly, just as you would acclimate fish. As noted above, you should be quarantining new fish before adding them to your main tank. If the tank this thread pertains to is your 30 gallon tank, it is way, way to small for a blue tang!

[benjidick]

I meant to say Purple Tang. I suppose they need larger tank also.

[kau_cinta_ku]

no tang will be comfortable in a 30 gal.
