- Well, they are mysteries to me. My wife and I have three tanks, all
- freshwater, and all (have been) stable for a couple of months. We've only
- had tanks for five months altogether, but we are fairly widely read in
- the public literature on keeping aquariums, tank chemistry, fish species,
- diseases, etc. We got through most of the normal beginner hurdles fairly
- easily. BUT...
-
- We left our tanks in the care of a neighbor over the holiday. We cleaned
- them before we left, checked Ph and ammonia, and did a periodic water
- change. The neighbor is a reasonably competant engineer and although no
- fishkeeper, not a fool either. He reports that all the fish in one tank
- were found dead the day after we left town, with the exception of the
- kuhli loach. This was about 28 hours after we left them alive and well.
- Both other tanks were fine. The death tank had a high ammonia level in it
- but Ph was 6.2 when we returned after a week. The kuhli recovered just
- fine after the neighbor put him in another tank. The neighbor froze the
- bodies in case we needed to examine them. All were bloated. What killed
- them?
-
- Our local experts think two things are possible - either the neighbor
- poisoned them :^) or something about the cleaning and water change did
- them in. The water was prepared with chlorine/ammine remover and aged for
- three days before use and heated to a matching temperature before the
- change, and changed the Ph by +.2, normal procedure for all tank changes,
- as well as being put in the other two tanks; I don't think the water did
- it. One of our experts says that a dead spot in the filter under a rock
- might have caused a collection of H2S which we released in the cleaning,
- and this may have poisoned the fish. We did a relatively thorough
- cleaning and had to return part of the siphoned water to the tank to
- avoid changing more than 1/4 of the tank. Any ideas???????
-
- Mystery #2: One of our tanks has a mat of fungus, whitish gooey
- threadlike mats in the top 1/2 to 1/4" of the gravel bed. The fish are
- OK, and the water tests normal, but it's hard to clean since the mats
- have to be broken up. What is this stuff, and what sin did I commit to
- have it visited upon me????
-
- Many thanks for any information.
