2 zebras dead
2 zebras dead
lost two zebras over the last two days. It appears that the two which died had small red blisters on the stomach of the zebra. Any suggestions please?
well i have had the fish in there for about a month or so maybe longer but i bought a few zebras on sunday and added them to the tank, the guy in the shop said i should lower my ph to 6.5 and gave me some acid. So i added that and it was lowered to 6.7, i then added fish could that be the problem? If it is something with filtration how could i solve it? Thanx
Hi AJ,
You really shouldn't be lowering your PH like that It's far better to acclimatise new additions to you tank water than the other way round. Why stress a whole tank full of fish on account of a few additions.
You must also remember that the PH scale is logorithmic, any decrease/increase is actually tenfold. Example: a drop of PH from 7.0 to 6.5 has made the water 50 times more acidic, get my drift. I still think that the anchor worm is to blame but the drop in PH would also have been a contributing factor in their deaths.

AJ,
I do not think that lowering the ph would be the cause, since my ph drops pretty quickly and then rises immediately on a water change,with no problems.
I would like to correct Adam though, he is right when he says that ph is logarithmic, but from ph 7 to ph 6.5 is only 5 times more acidic not 50 times. Ph 7 to ph 6 will be 10 times more acidic. ph 7 to ph 5 is 100 times more acidic and the same the other way around.
My own view is that it might have been Ammonia in the tank since it is prevalent above a ph of 7, if I have read your post right.
As I have said before I always put all new stock through a quarantine process, normally using one dose of TetraPond Medifin which is a combined bacteriacide and parasite killer.
I hope You did not remove the anchor worm alive from the fish as this normally leaves part of the worm still on the fish. Medicate first , then remove the dead worms after a few days.
Regards,
Des.
