Okay, I saved my friends Jardini from his un-cycled tank. Actually, the Jardini was the only survivor. Well, I put it in my 55 gallon quaratine tank and it is doing great. No sign of sickness, swimming fine and eating like a champ. I decided to add some fish from another established tank to the 55 gallon. For some reason, every fish I've put in with the Jardini has either died or became very sick looking like ammonia burn. The Jardini still is doing well but I don't know why the other fish aren't. The frustrating thing is that the fish put in with the Jardini gets sick within an hour. The fish look like they have ammonia burn but very quickly as soon as I put it in the tank, while the Jardini is just fine and healthy. The 55 gallon tank has been cycled and been running for about 6 months. The water parameters are: ammonia 0, nitrite 0, nitrate <10, PH 6. Can anyone tell me what in my measurements are killing all of my fish but not the Jardini. I've never had anything like this before so I'm stumped. I do see that the PH is alittle low but why is my Jardini the only one that's stable and healthy?
 
Perhaps there's a difference in ph of the tanks. The difference may cause an adverse reaction if just dunked in instead of being acclimated. Just a guess.

I acclimate the fish slowly by dripping water and the PH is very close to being the same by the time I finish the dripping. I've never had this happen before. I've tried different fish from the other tanks and the fish always have the same problem. I've tried large angel fish, oscars, parrot fish, and bala sharks. They all start to get sick within an hour but some do recover when I put the fish back to their original tanks. Just wondering why only the Jardini has no problems. I'll wait another month or so and try again. Wish me luck, Ed.

jardinis are pretty tough fish. Here in aus they are bred in large ponds that generally require heavy rains for filtration and water changes. I think the new fish that are getting introduced are stressed from the initial move, then they have to deal with a jar that probably isn't keen on having roommates.
 
I've watch the fish I put in with jardini, and I've never seen him even pay any attention to the other fish. I actually see the other fish slowly get sick. I've turned the lights off so the fish can get used to the tank and they still get sick. Maybe I'll wait another 2-3 weeks and try again.

It is clearly something in that tank's water, to which the Jar has acclimated and the others get schocked.

Are your ph testes okay, agewise? I would guess it has to do with ph schock.
 
Welll I WOULD move the jar ass soon as possible AND THEN start that 55 over again.... Problem solved and no more dead fish :)

Can you describe what you say looks like ammonia burn?

It is not that, i guess. I say your ph is way lowerr than you think ( which greatly reduces the toxicity in ammonia ) and your fish are dying of ph schock.
How are their eyes?
 
What I describe as ammonia burn is that the eyes start to film over, it seems to be losing it's slime, and the fish starts to stop swimming and would either float around or lay on the floor. If it is that my PH is too low, wouldn't it affect the Jardini too? Also, what can I do to bring my PH up if it's too low?

Perhaps the jar is beating up the other fish and has nothing to do with water quality.
