Hello all,
Yesterday I fed my juvenile fish (P. quindecim, Danio tinwini and Dario dario) whit vinegar eels, this morning all the fish, including the adult pair paro’s, where dead or dying ….. :ohmy: 🙁
does anyone have similar experience whit vinegar eels? I never had problems before, but it can’t be coincidence….Hi Teunis,
I’ve no experience with vinegar eels myself – when reading this, I believe I should keep it that way. I’am sorry to hear what happened to your fish.This is not entirely new to me, but the only experience similar that I heared of before referred to vinegar eels not purified carefully.
Living in vinegar, these organisms must be harvested for feeding fish by the one or other method in order to prevent vinegar from infesting the aquarium. Normally, this is no problem at all. But I have heared of one case where a considerable amount of vinegar entered the tank water and the fish died because of a substantial change of their environmental parameters.
But this is nothing to be alarmed about normally; it’s quite clear. That the vinegar eels should not be fed to the fish with a considerable amount of the vinegar is self-evident. Every method for raising vinegar-eels contains a method of harvesting them and does not include to add them together with their vinegar to the fish-tank.
Therefore I am sure that you did not do this either. I only reported about that mistake as having heared once; there is not big mistake that is never made by someone. But not in this case, of course. And therefore I am puzzled as others are by your bad experience. What could be the cause of it? I assert to your opinin that – normally – it can’t be coincidence.
I use a long necked bottle to harvest the eels; fill the bottle whit vinegar and eels up to the neck, put a dot of clean filter wool on top, and carefully fill the neck whit RO-water. a half hour later most of the eels are in the water, of course some vinegar will leach in, butt no significant amounts…
my only theory is that somehow an toxic mould got in to the culture, and trough de eels in to the fish. no idea if that’s actually possible..
Your method of harvesting the eels is mine too; I agree with you: That cannot be causal for your desaster.
I have no other theory than you have: There must have been some toxic pollution within that culture.
But what and how and why?
