Crayfish Died... Put Fish Into Same Tank But They're Dying Too Now

[Ogrt48]

So this mourning I woke up to find my nice 9 inch blue crayfish dead.. Just figured he died trying to molt or from age.. I did a decent water change and all. I bought 5 convicts at 7 pm tonight, its now 9 pm here. I added them like normal.. they were all perfect health.. When I put them into the tank that were really calm instead of hyper like normal..I just noticed 5 minutes ago that they can barely swim, one is upside down swimming.. They're eyes and lips are all messed up, it's if the water was eating them alive!? Wtf is in this water.. I filled an emergency tank with water from another good running tank and netted all the convicts and tossed em in the better water.. I hope they're ok =\

Can you tell us the stats in the tank they were all in when they were showing symptoms? And are they still showing them in the new tank? Also, what else is in that tank, if anything?

all i can say is evacuate the aquarium, clean thourghly, then use quick cure or ick away or any related product on the fish (not snails or shrimp) and then put them all back after cleaning

i had a fish die once, then i lost like 3 more fish and 7 snails, all bnecause of ick

Doing tests as we speak.
So far the convict that was swimming on it's side is now on it's side on the bottom of the tank.. It swims up every now and then.. One other convict is just swimming in place in the exact center of the tank.. I think he'll be fine, I dunno. The other 3 are in the right direction but just swimming with their bellys on the bottom of the tank.. It's like they were being torn apart..

Wow.. I really think they were being eaten alive for the two hours they were in there =\
The tests were fine except for ph.. It's too low to be on my chart. It's like urine yellow, so much acid. This makes no sense, that tank has been a perfect 7.4 for years, it was 7.4 this mourning... How the hell could this happen.. Can fish recover from this ? =\

 

[puddle_inc]

lie i said, best thing, find a temporary area for them, evacuate. use ick aqay, quick cure, a small pinch of sea salt and that should help. clean the tank with kaboom, limeaway, and bleach. rinse REALLY good, and that should help big time

If you have just added the fish and there dropping like flies it sounds like ph shock.
What was the ph of the lfs to your tank.
Need to look at size of tank in gallons or litres how many fish and which type.
Can you post full water stats.

Convicts are aggressive sure there not attacking one another.

I would check with the lfs on ph, according to that site 7.8 for them.

If the water had gone yellow sounds like your well overstocked to me, need an ammonia and nitrite reading.

The thing is, I had one of the convicts in my other tank for days, he was fine. I bought the other 4 today. It couldn't go to yellow from being overstocked, they're the only fish in there and they were only in there for 2 hours at the most before I noticed. Before them it was just the lonely crayfish. They should be 7.3-7.8, it varies depending onthe site. I've always kept convicts in 7.4 for a long time and they were always perfectly healthy and happy. Right now they're in the emergency tank in 7.4 ph water. I hope they make it =\\

It depends on what size tank you was keeping them in, fish can soon polute the water if the filter not up to the job.
Got to go now tired need my bed, hope some one else can help you, good luck.
But switching them from tank to tank will of stressed them more, and hope you matched temp and ph.

I think one has passed away.. I'm not sure so I just removed him and put him in a small solo container.. =\
Now the other 4, 1 of the larger pink convicts seems to be doing a lot better, he's swimming around slowly but fine, he's active now atleast. Another one is moving around slowly on just above the bottom but he's slowly doing better.. One is still just in the correct position but on the bottom of the tank just trying to breath.. Another one is on his side still breathing really hard.

This is all my fault. As soon as I put them into the water they all swam to bottom corners like they were being chased or something was scaring them.. I figured it was just them adjusting to the new home =\

How long did you climatise them for, it sounds like ph shock to water quality for fish to act like there doing.
Increase aeration in the tank, that about all you can do.
I would post this thread in the right part of the fish forum you will get more help as to be honest never kept them and no nothing on them.


Tolak was online try and pm him, hope he dosnt mind but he does know angel fish and other types like yours.

He's a good guy always willing to help if he can, good luck.

Heh, only one made it through the night =\
Atleast this one is looking and acting like the perfect pink convict again. Anyways after all the tests I decided it was ph shock, its the only test thats coming up wrong. I tried changing 50% of the water, the new water I put in was 7.2 I tested the tank again but the water change didn't seem to do anything, ph is still coming back bright yellow. Help?

Nevermind.. just dumped the tank, cleaned it well and set it up with all new stuff.
Hopefully this goes good.

Test before a water change not after it will give you false results.
If there is a high ammonia reading that can alter ph.
If it was ph shock the other fish is not out of the woods it can take well over a week to kill them.
Good luck.
Don't do large water changes the fish won't know if it coming or going you altering the ph all the time, small ones are best.

i really, really, really, really hope that you didn't listen to puddle inc's advice about cleaning solutions. and that if you did, you also rinsed every single item for a good 10-15 minutes before setting the aquarium back up.

NEVER use any cleaning agent on an empty aquarium other than vinegar, solutions of bleach, solutions of ammonia (or cleaners specially designed to be aquarium-safe). vinegar will just lower the pH for a little while, residue from bleach can be removed using dechlorinator and any ammonia traces will be removed once the nitrogen cycle starts back up. but when you use a typical housefold cleaner, you just don't know what sort of contaminants might be left behind to pollute your water.

(beyond that, kaboom and limeaway are merely solvents and would have essentially no antibacterial/antiseptic effects.)

I didn't, infact I just used plain old water to rinse everything since it was just a bad ph problem. Just tossed out all the gravel, then washed the tank in hot water and the decor also.
