I know someone, that had a lungfish, witch died, he said it was because of the PH and doing to many chages affected the PH.

I not convinced.

I personaly think the fish died from neglected. Anyone got info on Lungfish, that can help in my quest to see what this fish died of.

A friend of mine has had one forever, she says they're great fish. I know she adores hers, just bought him a 200 gallon.

Thanks Wuv, he was keeping his in a 4ft, I kept telling him to get a larger tank.

I shore he mentioned his PH was 15 :blink: :blink: :blink: but he said he had been messing with it, will try and find out. He's not the easyest person to comunicate with. He says he got fish left, and to be honest I worryed for there life's.
 
I don't think your friend would have any fish left, nor skin on any body part that went into the ph 15 tank.

this is the reason I don't beleave his story. as I said he not the easyest to understand, so may have read what he put wrong.
 
If your friends tap water has no buffering capacity it would be possible to lower/raise the pH drastically with a water change but it would actually be unfrequent water changes that would cause that. If the pH say drops from 7.4 (tap) to 6.4 in the tank over a month (no water changes), then, theoretically a 50% water change would put it back to 6.9 which is quite a change. Frequent water changes on the other hand would keep the tank pH very close to the tap pH since the pH wouldn't have long enough to drop before the next water change so you would see very little change in pH during a routine weekly water change.
 
I found out his PH is now 7.5 witch is fine, but still can't find out what it was before he changed the water.

Does antone know how long Lingfish life?? He said his was 15, is that old for this type of fish??
 
if it really was 15 then being kept in a 4ft for all that time probable would of been the end of him. where as 1 being kept in a much large tank would probable be able to live up to about 20-25 i would expect from that size fish.

ass rdd1952 large changes in water chemistry will only happen whne regular water changes aren't being done. it may of been the shock of nitrates. if he hadn't changed the wate for a while the the lung fish would of slowly been getting used to high nitrates then a large water change would suddenly drop these levels thus shocking the fish and possible dieing as a result along side the PH shock of a large water change.

Thats the basic problem I think. Most people that don't do water changes start messing with their pH because it starts dropping when the nitrates rise. Then the fish (which is already under stress) gets even more stressed out by the added chemicals. Then when the water is changed its a pretty big shock for the fish as the nitrates drop and the pH rises. The only comparison I can think of is bungee jumping with a chain for a cord, possible to survive it but not very likely.
 
ryeguy, that is not true at all. pH is just a measure of concentration: pH=15 implies that the concentration of H+ ions is 10^-15 moles per liter. Nothing impossible about that. It is just that it is exceptionally uncommon, you would need a base that dissassociates quite a great bunch to get over 14. Certainly, the common tests available at the LFS would not measure a pH of 15. Expensive lab-grade equipment would probably be needed.

p.s. there are acids that have negtive pHs as well. Acids that give up a lot of H+'s, but again, it is possible.

Thanks guys,

so would it be your opinion this fish died from neglect??

That would be my guess.
 
Sounds like the typical neglectful so called "fishkeeper" who really just wants something that looks cool but doesn't want to take care of it. Then they wonder why their fish die. I have to deal with them all the time in the store that I work in.
